The invention provides a process for preparing indole derivatives in which a compound containing an indole ring linked to an acylamido piperidine ring by a carbonyl alkylene group between the nitrogen of the piperidine and the 3-position of the indole is reduced with alkali-metal borohydride in special solvents so that the carbonyl group is reduced to a CH.sub.2 group.
该发明提供了一种制备吲哚衍生物的方法,其中包含一种化合物,该化合物包含一个吲哚环,通过一个碳酰胺基哌啶环与吲哚的3位之间的碳酰基烷基链相连。该化合物通过与碱金属硼氢化物在特殊溶剂中反应,使碳酰基还原为CH.sub.2基团。
