Participants

Reaction Steps

The 1-[2-(4-methylpiperazin-1-yl)ethyl]-3-(6-sulphanyl-1,3-benzothiazol-2-yl)urea was prepared according to the method described in Example 1b, but using 1 g of 1-(6-thiocyanato-1,3-benzothiazol-2-yl)-3-[2-(4-methylpiperazin-1-yl)ethyl]urea, 14 mg of potassium dihydrogen phosphate and 1.16 g of DL-dithiothreitol. 380 mg of 1-[2-(4-methylpiperazin-1-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:
