Procedure

A mixture of 2.6 parts of 3-chloro-6-[4-(2-chloroethyl)-1-piperidinyl]pyridazine, 1.9 parts of (cyclopropylmethyl) 4-hydroxybenzoate 1.1 parts of sodium carbonate and 94 parts of N,N-dimethylacetamide was stirred overnight at 110° C. After cooling, the reaction mixture was poured into water. The precipitated product was filtered off, washed with water and dissolved in trichloromethane. The organic layer was dried, filtered and evaporated. The residue was crystallized from 2-propanol. The product was filtered off and dried, yielding 2.9 parts (69.7%) of (cyclopropylmethyl) 4-[2-[1-(6-chloro-3-pyridazinyl)-4-piperidinyl]ethoxy]benzoate; mp. 134.0° C. (comp. 129).
