The present invention relates to compounds with the formulas (I), (II), and (III), or a pharmaceutically acceptable salt thereof: wherein T is a (4 to 10)-membered heterocyclyl selected from the group consisting of and wherein R1. R2 and R3 are as defined in the specification. The invention also relates to pharmaceutical compositions comprising the compounds of formulas (I), (II), and (III) and methods of treating a condition that is mediated by the modulation of the 11-β-hsd-1 enzyme, the method comprising administering to a mammal an effective amount of a compound of formulas (I), (II), and (III).

Magnesium methoxide (Mg(OCH3)2) and calcium chloride have been shown to facilitate the direct aminolysis of esters by ammonia to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters were converted to the corresponding carboxamides in good yields. Reactions have been run on a larger scale and without the safety liability inherent in the use of magnesium nitride (Mg3N2). Ammonium chloride
甲醇镁(Mg(OCH 3)2)和氯化钙已被证明可以促进氨将酯直接氨解为伯酰胺。将甲基,乙基,异丙基和叔丁基酯以良好的产率转化为相应的羧酰胺。反应已进行了较大规模,并且没有使用氮化镁(Mg 3 N 2)时固有的安全隐患。氯化铵和胺盐酸盐已成功用于代替甲醇与甲醇镁。
