To 0.065 g (0.22 mmol) of 7-(hydroxymethyl)-N-mesityl-1,3-benzothiazol-2-amine in 2 mL of dichloromethane was added 58 μL (0.72 mmol) of pyridine and 0.24 mL (0.24 mmol) of phosphorous tribromide (1 M in dichloromethane). The reaction was stirred at room temperature for 8 h and quenched with saturated sodium bicarbonate. The organic layer was washed with brine, dried over sodium sulfate, filtered and concentrated to give 0.045 g (57%) of the title compound that was used without further purification.
