Procedure

A solution of the above crude 2-(3-furyl)ethylamine and 4.24 g (39.9 mmol) of benzaldehyde in 50 ml of methanol was stirred at room temperature for 0.5 hours. The reaction mixture was cooled with ice-water; 1.89 g (49.9 mmol) of sodium borohydride was added portionwise followed by stirring at room temperature for 1 hour. The reaction mixture was poured into aqueous sodium hydroxide and extracted with dichloromethane 3 times. The combined organic layer was dried over anhydrous magnesium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (hexane/ethyl acetate=1/1 to ethyl acetate) to yield the desired product.
