The present invention relates to a process for the preparation of indole derivatives, particularly those, which are useful as pharmaceutical intermediates. The process involves formation of hydrazone derivative between a phenyl hydrazine and a ketone amine, followed by cyclisation to give desired 2,3-substituted indole derivative in the presence of acid catalyst.
本发明涉及一种制备吲哚衍生物的方法,特别是那些作为药物中间体有用的衍生物。该方法涉及在酸催化剂存在下,通过苯基肼和酮胺之间的缩醛衍生物的形成,然后进行环化反应,得到所需的2,3-取代吲哚衍生物。
