Abstract
The invention comprises 2-acylamino-1:3:4-thiadiazole-5-sulphonamides of the formula: <FORM:0844946/IV(b)/1> wherein R1 is a hydrogen, alkyl or monocyclic aralkyl and R2 is alkyl or monocyclic aralkyl and their preparation by chlorinating the appropriate 2 - (N - substituted) acylamino - 5 - benzylmercapto-1:3:4-thiadiazole, which maybe obtained by the action of a halide R2-Halogen on a 2-acylamino-5-benzylmercapto-thiadiazole, to give a 2-(N-substituted-acylamino-1:3:4-thiadiazole sulphonyl chloride, and reacting the latter with ammonia. Specified products include 2-N-methyl-acetyl-, N-methyl-formyl-, N-methyl, propionyl-, N-propyl-butyryl-, N-benzyl-acetyl and N-methyl-phenacetyl- 1:3:4-thiadiazole-5-sulphonamide and the corresponding intermediate compounds.
