Procedure

After dissolving 1.12 g of 4-[2-(2-fluorophenyl)ethyl]-3-methoxypyridine in 10 ml of acetonitrile, 0.63 ml of benzyl bromide was added, the mixture was stirred for 2 hours at 50° C., and the solvent was distilled off under reduced pressure. The residue was dissolved in 20 ml of methanol, and then 552 mg of sodium borohydride was added while cooling on ice and the mixture was stirred for 1 hour. Water was added to the reaction solution, and extraction was performed with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtered with NH silica gel. The solvent was distilled off under reduced pressure to obtain the title compound (1.26 g, 80% yield).
