Procedure

70 g (0.28 mole) of 2-tert.-butyl-6-isothiocyanobenzthiazole are dissolved in 1200 ml of ether and 33 g (0.33 mole) of 4-methylpiperazine are added dropwise, while stirring. The mixture is stirred for 1 hour, filtered and washed first with ether, then with petroleum ether. 2-tert.-butyl-6-[(4-methylpiperazin-1-yl)-thiocarbonylamino]-benzthiazole having a melting point of 176-177° is obtained: ##STR13##

Workup
