a solution of 5 mg of potassium dihydrogen phosphate in 1.1 cm3 of water at 20° C., followed by 480 mg of DL-dithiothreitol, are added to a white suspension of 280 mg of methyl (6-thiocyanato-1,3-benzothiazol-2-yl)-carbamate in 11 cm3 of ethanol at 20° C. The white suspension is stirred for 18 h at reflux. The reaction mixture is cooled to 20° C., then 10 cm3 of water are added and the mixture is stirred for 15 minutes. The precipitate is spin-filter-dried and then washed with large volumes of water. 231 mg of methyl (6-sulphanyl-1,3-benzothiazol-2-yl)carbamate are obtained in the form of a cream powder, the characteristics of which are as follows:
