실험 절차

21 g (0.076 mole) of 2-tert.-butyl-6-isothiocyano-5-methoxy-benzthiazole are dissolved in 400 ml of acetone and a solution of 12 g (0.092 mole) of N-(2-hydroxyethyl)-piperazine in 40 ml of acetone is added dropwise. The mixture is stirred for 2 hours, cooled to 0° , filtered and washed with acetone, then with ether and finally with petroleum ether. 2-tert.-butyl-5-methoxy-6-{[4-(2-hydroxyethyl)-piperazin-1-yl]-thiocarbonylamino}-benzthiazole having a melting point of 161-162° is obtained.
