Procedure
A solution of 2.0 g of 2-tert-butyl-6-isothiocyanato-5-(4-methylpiperidin-1-yl)benzothiazole and 0.78 g of 1-acetyl-piperazine in 30 ml of chloroform is stirred for 30 minutes and the product triturated with petroleum ether to obtain 6-[(4-acetyl-piperazin-1-yl)thiocarbonylamino]-2-tert-butyl-5-(4-methylpiperidin-1-yl)benzothiazole, melting at 187°-190°.
