摘要
本文采用邻氰基苯甲醛为原料,与水合肼反应生成肼苯哒嗪(Ⅱ),然后(Ⅱ)与异丙叉丙酮缩合,得到布酞嗪。此工艺过程简单、操作简便、收率较高。
This paper described the synthetic method of Budralazine by using o-cyanobenzaldehyde (Ⅰ) as the raw material. (Ⅰ) reacted with 50% hydrazine hydrate to form hydralazine(Ⅱ),and then(Ⅱ) reacted with mesityl oxide to give Budralazine. This process is simplified and the product was obtained in high yield.
