Procedure

0.005 mol of 4,5-dichlorophthalic anhydride and 0.005 mol of 1-(4-aminobutyl)-4-(5-phenyl-2-pyrimidinyl)-piperazine in 20 ml of absolute pyridine are boiled under reflux, under an atmosphere of N2, for several hours. After cooling, the product which has crystallised out is filtered off and washed with isopropyl ether.
