Procedure

0.06 mol of N-(4-(4-(2-pyrimidinyl)-1-piperazinyl)butyl)-2-nitrobenzenesulphonamide is dissolved in 500 ml of MeOH, 2.4 g of 5% Pd-C are added, the mixture is heated to boiling and 0.17 mol of hydrazine hydrate in 50 ml of MeOH is added dropwise within 15 minutes. After boiling for a further 30 minutes, the mixture is filtered, the filtrate is evaporated, the residue is taken up in diethyl ether, washed with water, evaporated again and crystallised from isorpopanol/isopropyl ether.
