Reaction Steps

A solution of N-formyl-1-[1-(4-chlorophenyl)-cyclobutyl]-4-ethoxybutylamine (1.6 g) in dry toluene (40 ml) was added dropwise to a stirred 70% solution of sodium bis-(2-methoxyethoxy)aluminium hydride in toluene sold under the trade name Red-Al (6 ml) in dry toluene (15 ml) at ambient temperature, under nitrogen. The mixture was stirred at 50° C. for 3 hours then cooled and water (20 ml) and then 5N sodium hydroxide solution (15 ml) were added. The mixture was extracted with ether and the extracts dried and evaporated to give an oil which was treated with an ethereal solution of maleic acid to give a salt which was recrystallised from propan-2-ol to give N-methyl-1-[1-(4-chlorophenyl)cyclobutyl)-4-ethoxybutylamine maleate (m.p. 102-103° C.).
