4-Methoxy-2-nitroaniline was converted in seven steps to 8-amino-6-methoxycinnoline with an overall yield of 33%. Several attempts to introduce a 5-aminopentan-2-yl side-chain in the amino-group to give 2-azaprimaquine were unsuccessful.
将4-甲氧基-2-硝基苯胺分七个步骤转化为8-氨基-6-甲氧基肉桂酸,总产率为33%。在氨基中引入5-氨基戊烷-2-基侧链以产生2-氮杂伯氨喹的几种尝试均未成功。
