  The present invention relates to a method of preparing an alkylated salicylamide from a protected and activated salicylamide (hereinafter referred to as a “protected/activated salicylamide”). The method comprises the steps of (a) alkylating the protected/activated salicylamide with an alkylating agent to form a protected/activated alkylated salicylamide, and (b) deprotecting and deactivating the protected/activated alkylated salicylamide, simultaneously or in any order, to form the alkylated salicylamide. The alkylated salicylamides prepared by this method are suitable for use in compositions for delivering active agents via oral or other routes of administration to animals.

  本发明涉及一种从受保护和活化的水杨酰胺（以下简称为“受保护/活化的水杨酰胺”）制备烷基化水杨酰胺的方法。该方法包括以下步骤：（a）用烷基化试剂烷基化受保护/活化的水杨酰胺，形成受保护/活化的烷基化水杨酰胺；以及（b）去保护和去活化受保护/活化的烷基化水杨酰胺，同时或以任何顺序，形成烷基化水杨酰胺。通过这种方法制备的烷基化水杨酰胺适用于用于通过口服或其他途径向动物传递活性药剂的组合物中。

  The present invention provides a fast, high yield method for preparing salicylamide intermediates. The method comprises reacting a C 4 or higher alkyl ester of salicylic acid or derivative thereof with at least one amine selected from the group consisting of monoalkylamines, dialkylamines, ammonia, and any combination of any of the foregoing in alcohol to yield the sali-cylamide. The C 4 or higher alkyl ester of salicylic acid or a derivative thereof is preferably prepared by reacting salicylic acid or a derivative thereof with a C 4 or higher alcohol in presence of at least one of sulfuric acid, a sulfonic acid, and a mineral acid. This process for preparing salicylamide intermediates from salicylic acid or derivative thereof generally has a cycle time of about 2 days, and yields about 95% of a 99% pure material. In comparison, when a C 3 or lower alkyl ester is used in lieu of the C 4 or higher alkyl ester, the process generally has a cycle time of 7-9 days and yields about 60% of a 95% pure material. Methods of preparing an alkylated salicylamide are also provided.

  本发明提供了一种快速、高产量的制备水杨酰胺中间体的方法。该方法包括将水杨酸的C4或更高烷基酯或其衍生物与来自单烷基胺、二烷基胺、氨和上述任何组合的至少一种胺在醇中反应，以产生水杨酰胺。水杨酸的C4或更高烷基酯或其衍生物通常是通过将水杨酸或其衍生物与C4或更高醇在硫酸、磺酸和矿酸中的至少一种存在下反应制备的。从水杨酸或其衍生物制备水杨酰胺中间体的这一过程通常具有约2天的周期时间，并产生约95%的99%纯度物质。相比之下，当使用C3或更低烷基酯代替C4或更高烷基酯时，该过程通常具有7-9天的周期时间，并产生约60%的95%纯度物质。还提供了制备烷基化水杨酰胺的方法。

  The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. The delivery agents have the formula 1 wherein R 1 , R 2 , R 3 , and R 4 are indepedently hydrogen, halogen, C 1 -C 4 alkyl, or C 1 -C 4 alkoxy; and R 5 is a substitued or unsubstituted C 2 -C 16 alkylene, substituted or unsubstituted C 2 -C 16 alkenylene, substituted or unsubstituted C 1 -C 12 alkyl(arylene), or substituted or unsubstituted aryl(C 1 -C 12 alkylene). The hydrates and solvates of present invention also have surprisingly greater efficacy for delivering active agents, such as heparin and calcitonin, than their corresponding monosodium salts and free acids. The present invention provides an alcohol solvate, such as ethanol solvate, of a disodium salt of a delivery agent of the formula above. The invention also provides a hydrate of a disodium salt of a delivery agent of the formula above. Preferred delivery agents include, but are not limited to, N-(5-chlorosalicyloyl)-8-aminocaprylic acid (5-CNAC), N-(10-[2-hydroxybenzoyl]amino)decanoic acid (SNAD), and sodium N-(8-[2-hydroxybenzoyl]amino)caprylate (SNAC). The invention also provides methods of preparing the disodium salt, ethanol solvate, and hydrate and compositions containing the disodium salt, ethanol solvate, and/or hydrate.

  发明者发现，某些传递剂的二钠盐比相应的单钠盐具有更出色的传递活性剂的功效。此外，发明者还发现这些传递剂的二钠盐与乙醇形成溶剂合物，与水形成水合物。传递剂的公式为1，其中R1、R2、R3和R4分别为氢、卤素、C1-C4烷基或C1-C4烷氧基；R5是取代或未取代的C2-C16烷基、取代或未取代的C2-C16烯基、取代或未取代的C1-C12烷基（芳基）或取代或未取代的芳基（C1-C12烷基）。本发明的水合物和溶剂合物比它们的相应单钠盐和自由酸具有更出色的传递活性剂的功效，例如肝素和降钙素。本发明提供了公式如上的传递剂的二钠盐的醇溶剂，例如乙醇溶剂。本发明还提供了公式如上的传递剂的二钠盐的水合物。优选的传递剂包括但不限于N-(5-氯水杨酰基)-8-氨基己酸（5-CNAC）、N-(10-[2-羟基苯甲酰基]氨基)癸酸（SNAD）和N-(8-[2-羟基苯甲酰基]氨基)癸酸钠（SNAC）。本发明还提供了制备二钠盐、醇溶剂和水合物以及含有二钠盐、醇溶剂和/或水合物的组合物的方法。
