Reaction Conditions

Reaction Steps

A mixture of 7.5 parts of 1-(3-chloropropoxy)-4-fluorobenzene, 10.5 parts of N,N-diethyl-2-[(4,4-dimethoxy-3-piperidinyl)oxy]ethanamine, 7 parts of N,N-diethylethanamine, 1 part of potassium iodide and 90 parts of N,N-dimethylformamide was stirred for 17 hours at 60° C. The reaction mixture was poured onto water and the product was extracted with trichloromethane. The extract was washed with water, dried, filtered and evaporated. The residue was purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) saturated with ammonia, as eluent. The pure fractions were collected and the eluent was evaporated. The residue was converted into the hydrochloride salt in acetonitrile and 2-propanol. The whole was evaporated and the residue was taken up in acetonitrile. The solution was evaporated, yielding 14 parts (75%) of N,N-diethyl-2-[[1-[3-(4-fluorophenoxy)propyl]-4,4-dimethoxy-3-piperidinyl]oxy]ethanamine as a residue (intermediate 115).
