Procedure

To a solution of 2-benzothiazolthiol (250 g) in N,N-dimethylformamide (1 l) was added triethylamine (208 ml) under ice-cooling and dropwise a solution of benzyl bromide (178 ml) in N,N-dimethylformamide (300 ml) and the mixture was stirred for 40 minutes. The resulting solution was poured into water (10 l) and the formed precipitate was separated by filtration and dissolved in dichloromethane (3 l). After drying over anhydorpus magnesium sulfate, dichloromethane was removed in vacuo to give 378 g of the objective compound.
