Procedure

4,4-Diethoxy-1-((S)-1-phenyl-ethyl)-(R)-2-aminomethyl-piperidine (2.25 g, 7.37 mmol), and triethyl amine (1.49 g, 14.7 mmol) in acetonitrile (50 ml) was heated to 60° C. before 2-chlormethyl-6-methoxy-benzoic acid methyl ester (1.58 g, 7.37 mmol) in acetonitrile (25 ml) was added over the course of 1.5 hour. After addition the reaction mixture was stirred overnight at 60° C. The solvent was removed in vacuo and the residue was dissolved in dichloromethane (50 ml) and washed with saturated sodium bicarbonate. After drying (MgSO4), filtration and evaporation of the solvent in vacuo the residue was subjected to flash column chromatography (SiO2, ethyl acetate-light petrol ether (1:1)) to give 2.3 g (69%) of 2-(R)-(7-methoxy-2,3-dihydro-isoindol-1-one-2-ylmethyl)-4,4-diethoxy-1-(1-(S)-phenyl-ethyl)-piperidine.
