6-ethoxycarbonyl-2-methylbenzothiazole (2.09 g) prepared according to the method described in J. Gen. Chem. vol. 5, pp. 260-266 (1945) was subjected to bromination with NBS (1.78 g) in carbon tetrachloride (30 mg). Then, the product was caused to react with dimethylamine to yield a new compound of 6-ethoxycarbonyl-2-dimethylaminomethylbenzothiazole (0.8 g). Then, the compound was provided with the same treatment as that described in Examples 49-51 to yield 6-[(2-aminoethyl)thiomethyl]-2-(dimethylaminomethyl)benzothiazole.2hydrobromide (1.2 g).
