Reaction Steps

Sodium borohydride (2.5 g) was added portionwise to a stirred solution of methoxyacetic acid (26.4 g) in toluene (300 ml) under an atmosphere of nitrogen and stirring was continued for 16 hours. A solution of 1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutylamine (5 g) in toluene (50 ml) was then added and the mixture was heated under reflux with stirring for 24 hours. After cooling the reaction mixture, water (200 ml) was added and the mixture was basified with 16N aqueous sodium hydroxide solution. The product was extracted into ether and the extracts were washed with water, dried and evaporated to give a brown oil which was dissolved in ether (30 ml). A solution of maleic acid (4.8 g) in ether (250 ml) was added. The solid which precipitated was collected, dried and recrystallised from ethyl acetate with hot filtering to give N-(2-methoxyethyl)-1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutylamine maleate (m.p. 131°-133° C.).
