ABSTRACT

6-Bromo-8-chlorosulfonylquinazoline-2,4(1H,3H)-dione was obtained from 6-bromoquinazoline-2,4(1H,3H)-dione and chlorosulfonic acid in place of the expected 6-bromo-7-chlorosulfonyl-quinazoline-2,4(1H,3H)-dione. Interaction of the product with water, alcohols, ammonia, aliphatic and heterocyclic amines gave 6-bromo-8X-quinazoline-2,4(1H,3H)-diones (X = SO2OH, SO2OAlk, SO2NR1R2), and, by reduction with SnCl2·2H2O in hydrochloric acid, 6-bromo-8-mercaptoquinazoline-2,4-dione was obtained.
