実験手順

2-Fluoro-biphenyl-4-carbaldehyde (1 gm, 5 mmole), NaBH4 were dissolved in ethanol stirred for 2 hrs, NaOH 10% was added, ethanol was evaporated, the reaction mixture was extracted with ethyl acetate, the ethyl acetate extract was dried with Na2SO4 and evaporated to produce white solid (0.8 gm, 80%). H1-NMR INOVA-500 (CDCl3) δ 2.266 (s, 1H), 4.683 (s, 2H), 7.142-7.168 (m, 2H), 7.339-7.442 (m, 4H), 7.519-7.535 (m, 2H).
