Procedure

0.37 g (7.7 mmol) of sodium hydride (50% in mineral oil) is added batchwise to a solution of 1.5 g (7.06 mmol) of 2-mercapto-6-nitro-benzothiazole and then stirred for 30 minutes at 50° C. Then 1.45 g (7.4 mmol) of 4-bromomethylbenzonitrile is added dropwise and stirred for a further hour at 50° C. The re-action mixture is mixed with 30 ml of ethyl acetate and 70 ml of 14% sodium chloride solution, whereupon a large proportion of the title compound is obtained as a beige precipitate. The organic phase is concentrated in vacuo, the crude product precipitated is triturated with diethyl ether and the liquid phase is separated off. The solid obtained is combined with the beige precipitate.
