Sandmeyer 반응으로 5-aminouracil로부터 5-iodo-, 5-chloro-및 5-bromouracil을 간편하게 합성하는 방법을 세로히 마련하였다. 이 방법에 따르면 5-halouracil이 75% 이상의 좋은 수율로 얻어지며, 부반응을 수반하지 않으므로 생성물의 정제가 쉽고 편리하게 5-halouracil을 얻을 수 있다는 이점이 있다.

A new conventional method for the preparation of 5-iodo-, chloro-and bromouracil by Sandmeyer reaction was described. According to this procedure, 5-halouracils have been prepared in high yields(up to 75%) without any difficulties to remove of impurities. No appreciable competing reaction was observed.
