The 2-morpholin-4-ylethyl (6-thiocyanato-1,3-benzothiazol-2-yl)carbamate was prepared according to the method described in Example 9c, but using 654 mg of phenyl (6-thiocyanato-1,3-benzothiazol-2-yl)carbamate and 0.27 cm3 of 2-morpholin-4-ylethanamine. The residue obtained is chromatographed on an Analogix cartridge of 40 g of silica 15-40 μm, elution being carried out with a gradient of dichloromethane then 95/5 dichloromethane/methanol. 729 mg of 2-morpholin-4-ylethyl (6-thiocyanato-1,3-benzothiazol-2-yl)carbamate are thus obtained in the form of a white solid, the characteristics of which are as follows:
