After the mixture had been flushed with nitrogen, hydrogen was passed in. After some hours, the uptake of hydrogen (44 1) had ended, and the mixture was flushed with nitrogen again, the catalyst was filtered off and the filtrate was concentrated. 135.6 g of 4-(β-benzothiazol-2-yl-ethyl)-aniline of melting point 79°-81° C. were obtained.
