To a mixture of (2R)-1-[4-(5-fluoro-2-methoxy-phenyl)-1,2,3,6-tetrahydropyridin-1-yl]-2-methylamino-3-phenyl-propan-1-one hydrochloride (0.41 g, 1.0 mmole) in 20 mL of tetrahydrofuran at 0° C. under N2 was added of triethylamine (0.14 mL, 1.0 mmol), followed by slow addition of 1.9 mL (1.9 mmole) lithium aluminum hydride (1 M solution in THF). After addition, the cooling bath was removed and the mixture was stirred at room temperature for 2.5 hours. The reaction was quenched by the slow addition of saturated NH4Cl solution and the mixture was filtered through a celite pad. The solution was concentrated to afford 0.36 g (100% {(1R)-1-benzyl-2-[4-(5-fluoro-2-methoxy-phenyl)-1,2,5,6-tetrahydropyridin-1-yl]-ethyl}-methyl-amine as a yellow oil which was used without further purification.
