Reaction Steps
A mixture of 16.7 parts of ethyl 4-[[4-(6-chloro-3-pyridazinyl)-1-piperazinyl]methyl]benzoate and 11.3 parts of 2-hydroxyethanamine was stirred for 4 hours at 140° C. After cooling, the reaction mixture was stirred into water. The precipitated product was filtered off, washed with 2,2'-oxybispropane and converted into the hydrochloride salt in 2-propanol. The salt was filtered off, washed with 2-propanol and 2,2'-oxybispropane and dried at 70° C., yielding 9.7 parts (51.1%) of 4-[[4-(6-chloro-3-pyridazinyl)-1-piperazinyl]methyl]-N-(2-hydroxyethyl)benzamide monohydrochloride; mp. >260° C. (decomp.) (comp. 167).
