This invention relates to a novel process for preparing 2-amino-8-alkoxybenzazepines. The process involves cyclizing an intermediate alkoxybenzene-ethanimidate with a catalytic amount of one or more acids, optionally in the presence of one or more non-reactive solvents.
本发明涉及一种制备 2-
氨基-8-烷氧基苯并氮杂卓的新工艺。 该工艺包括用一种或多种酸催化中间体烷氧基
苯乙酸乙酯环化,可选择在一种或多种非反应性溶剂存在下进行。
