実験手順
9.3 g 3,6-dichloro-4-piperazin-1-yl-pyridazine (cf. 10.2) and 6.5 g sodium acetate are suspended in 100 ml of methanol and hydrogenated with 1 g Pd/C 10% at ambient temperature. The catalyst is suction filtered and the filtrate is evaporated to dryness. The product is extracted with chloroform, washed with sodium hydroxide solution and precipitated as the hydrochloride with an ethereal HCl solution. 8.6 g (V-4) are obtained. M.p.>300° C.
