A process for the preparation of compounds of formula ##STR1## and pharmaceutically acceptable salts thereof; wherein X is --CH.sub.2 --, --CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --C.tbd.C-- or --CH.sub.2 O-- (where O is linked to Z); Z is a hydrophobic anchor R.sub.1 is hydrogen, alkyl, cycloalkyl or aryl; comprising the steps of: (A) reacting a compound of formula ##STR2## with a compound of formula ##STR3## or a compound of formula ##STR4## in the presence of an amine base or an alkali metal hydride in an organic solvent to form a compound having the formula ##STR5## (B) heating the compound of formula IX at a temperature of from about 100.degree. C. to about 200.degree. C., to form a compound of formula ##STR6## and (C) quenching the compounds of formula VIII with an acid provides the compounds of formula I.
一种制备公式##STR1##化合物及其药用可接受盐的方法;其中X为--CH.sub.2 --,--CH.sub.2 CH.sub.2 --,--CH.sub.2 CH.sub.2 CH.sub.2 --,--CH.dbd.CH--,--C.tbd.C--或--CH.sub.2 O--(其中O与Z连接);Z为疏水锚,R.sub.1为氢、烷基、环烷基或芳基;包括以下步骤:(A)在有机溶剂中,在胺基或碱金属氢化物的存在下,将式##STR2##的化合物与式##STR3##或式##STR4##的化合物反应,形成具有式##STR5##的化合物;(B)将式IX的化合物加热至约100℃至约200℃的温度,形成式##STR6##的化合物;(C)用酸淬灭式VIII的化合物,提供式I的化合物。
