Procedure

A mixture of 10.1 parts of 5-aminoisothiazole-3,4-dicarboximide and 70 parts of concentrated aqueous ammonia solution is stirred for 2 hours at room temperature, and the colorless precipitate is then filtered off under suction, washed with water and dried to give 9.3 parts (83% of theory) of 5-aminoisothiazole-3,4-dicarboxamide.
