This invention concerns a process for preparing 2- benzazepine compounds which inhibit the enzyme phenylethanolamine N-methyltransferase and show activity in reducing anxiety. The compounds produced have substituents in the 8- and/or 9-positions, and optionally substituents in the 1- and 2-positions. The compounds are prepared by debenzylating an appropriately substituted N-benzyl 2-benzazepine with optional acylation and reduction, or with optional ozidation and alkylation of the debenzylated product to introduce 2- and 1-position substituents, respectively. Acid addition salts of the compounds are also prepared.
本发明涉及一种制备 2-苯并氮杂卓化合物的工艺,该化合物可抑制苯乙醇胺 N-甲基转移酶,并具有减轻焦虑的活性。所制备的化合物在 8 位和/或 9 位上有取代基,在 1 位和 2 位上也有取代基。这些化合物的制备方法是将适当取代的 N-苄基 2-苯并氮杂卓进行去苄基化,然后进行任选的酰化和还原,或对去苄基化产物进行任选的羰基化和烷基化,以分别引入 2 位和 1 位取代基。还可制备这些化合物的酸加成盐。
