反応手順

To a solution of 4-benzyloxy-3-chlorobenzaldehyde (4.9 g, 20 mmol) and trimethyl(trifluoromethyl)silane (4.4 mL, 30 mmol) in THF (0.10 L) was added a solution tetrabutylammonium fluoride (1.0 M in THF, 2.0 mL). After the reaction was stirred at 25° C. for 3 h, it was acidified with 2 N HCl to pH 2, diluted with ethyl acetate and washed with brine. The organic phase was dried and concentrated and the residue was purified by chramotography on silica gel eluting with 8:2 hexane:ethyl acetate to give 1-(4-benzyloxy-3-chlorophenyl)-2,2,2-trifluoroethanol.
