Procedure

A mixture of 3.6 parts of 3-chloro-6-(1-piperazinyl)pyridazine monohydrochloride, 5.3 parts of sodium carbonate and 90 parts of N,N-dimethylacetamide was stirred for a while at 60° C. Then there were added 3 parts of (3-bromopropyl)benzene and the whole was stirred overnight at 60° C. The reaction mixture was poured into water. The product was filtered off and converted into the hydrochloride salt in 2-propanol. The salt was filtered off and dried, yielding 3.2 parts (60%) of 3-chloro-6-[4-(3-phenylpropyl)-1-piperazinyl]pyridazine monohydrochloride; mp. 207.3° C. (compound 226) In a similar manner there were also prepared:
