Procedure
1.5 g of 2-bromo-5-chloro-2-methylindan-1-one are dissolved together with 460 mg of thiourea in 50 ml of triacetone and boiled under reflux for 8 h. The precipitate is filtered off with suction, washed with acetone and dried in vacuo. 2-Amino-6-chloro-8a-methyl-8,8a-dihydroindeno[1,2-d]thiazol-3a-ol hydrobromide is obtained and melts at 229° C. with decomposition.
