Reaction Conditions

Reaction Steps

After dissolving 2.72 g of 2-(3-methyl-2-thienyl)-1-(4-pyridyl)ethanone in 15 ml of toluene, 1.79 ml of benzyl bromide was added, the mixture was stirred for 7 hours at 110° C. and the precipitate was filtered out. The filtered substance was dissolved in 60 ml of methanol, 1.42 g of sodium borohydride was added in small portions at a time while cooling on ice, and the mixture was stirred for 1 hour. The reaction solution was distilled off under reduced pressure, water was added, and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (solvent: n-hexane/ethyl acetate) to obtain the title compound (2.85 g, 73% yield).
