A facile conversion of the methyl group of 1,3-disubstituted 5-amino-6-methyluracils (1a-c) or 4-amino-antipyrine (5) to a cyano group was carried out via fused isoselenazole ring-formation followed by nitration and reduction.
通过稠合的异戊烯唑环形成,然后硝化,将1,3-二取代的5-氨基-6-甲基尿嘧啶(1a-c)或4-氨基-安替比林(5)的甲基轻松转化为氰基和减少。
