Participants

Reaction Steps

5,6-Dimethylindan-1-one is converted as described above for the other indan-1-ones into 2-bromo-5,6-dimethylindan-1-one. This is reacted with an equivalent amount of thioacetamide in acetone. The precipitate consisting of the hydrobromide of 2,5,6-trimethyl-8,8a-dihydroindeno[1,2-d]thiazol-3a-ol is heated in glacial acetic acid and affords, after removal of the solvent and treatment with diisopropyl ether, 2,5,6-trimethyl-8H-indeno[1,2-d]thiazole hydrobromide with a melting point of 290° C.
