Reaction Steps
0.028 mol of 2-(4-bromobutyl)-1,3,2-benzodithiazole 1,1,3,3-tetroxide and 0.056 mol of 1-(2-pyrimidinyl)piperazine in 125 ml of absolute DMF are stirred at 25° C. for 6 hours. The mixture is then cooled to 0° C., 150 ml of water are added dropwise with stirring, and the substance which has crystallised out is filtered off with suction. The product is purified by chromatography on silica gel; the eluting agent is ethyl acetate.
