Procedure

A mixture of 8.9 parts of 3,6-dichloropyridazine, 8.6 parts of 3-(2-chloroethyl)-pyrrolidine hydrochloride, 21.2 parts of sodium carbonate and 235 parts of N,N-dimethylformamide was stirred overnight at about 65° C. The reaction mixture was poured into ice water and the product was extracted with dichloromethane. The extract was dried, filtered and evaporated, yielding 12.2 parts (99.1%) of 3-chloro-6-[3-(2-chloroethyl)-1-pyrrolidinyl]pyridazine as a residue (int. 94).
