実験手順

1.0 g (3.43 mmol) of 4-(benzyloxy)-3-bromobenzaldehyde [Lit.: R. Baker et al., J. Chem. Soc. Chem. Commun. 14, 1102-1104 (1987)] is initially charged in 10 ml of tetrahydrofuran. At 0° C., 0.04 g (1.03 mmol) of sodium borohydride is added. The reaction mixture is stirred at room temperature for 3 hours. Saturated ammonium chloride solution is then added, and the mixture is extracted twice with ethyl acetate. The combined organic phases are dried with sodium sulphate and the solvent is removed under reduced pressure. This gives 0.98 g (97% of theory) of [4-(benzyloxy)-3-bromophenyl]methanol.
