Reaction Steps

N-[2-(4-Carbomethoxymethoxyphenyl)-1-methylethyl]-2-(2-hydroxyethoxy)-2-(3-chlorophenyl)ethanamine (3.0 g) in dry tetrahydrofuran (30 ml) was added dropwise, with stirring, to a suspension of lithium aluminium hydride (1.0 g) in dry tetrahydrofuran (30 ml) and the resultant mixture heated under reflux for 3 hours. After cooling, water (1 ml), 10% aqueous sodium hydroxide (1 ml) and water (2 ml) were added carefully. Filtration and evaporation of the filtrate to dryness gave an oil which was converted to its hydrochloride salt by treatment with ethereal hydrogen chloride. Recrystallisation from ethyl acetate-methanoldiethyl ether gave the title compound, mp 86°-90° C. as a 49:51 mixture of diastereoisomers.
