(E)-3-(2-Pyridyl)acrylonitrile (0.50 g, 3.8 mmol) was dissolved in 2-propanol (10 ml), and sodium borohydride (0.50 g, 13.2 mmol) was added thereto. The reaction mixture was stirred at 80° C. for 14 hrs and cooled under ice cooling condition, combined with water, concentrated to the half amount and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was subjected to a silica gel (25 g) column chromatography. The fractions eluted with hexane-ethyl acetate (1:1, v/v) were collected and concentrated to give the titled compound (0.42 g, 82%).
