The 1-{2-[(2R,6S)-2,6-dimethylmorpholin-4-yl]ethyl}-3-(6-sulphanyl-1,3-benzothiazol-2-yl)urea was prepared according to the method described in Example 1 b, but using 640 mg of 2-[({2-[(2R,6S)-2,6-dimethylmorpholin-4-yl]ethyl}carbamoyl)amino]-1,3-benzothiazol-6-yl thiocyanate, 7 mg of potassium dihydrogen phosphate and 729 mg of DL-dithiothreitol. 597 mg of 1-{2-[(2R,6S)-2,6-dimethylmorpholin-4-yl]ethyl}-3-(6-sulphanyl-1,3-benzothiazol-2-yl)urea are thus obtained in the form of a white solid, the characteristics of which are as follows:
