実験手順

To a solution of (4-formyl-2,6-dimethoxyphenoxy)-acetate methyl ester (1.5 g, 5.9 mmol) in THF (30 mL, 0.2 M) was added LiAlH4 (403 mg, 10.6 mmol) at water temperature. The reaction mixture was stirred for 6 hours at room temperature, followed by addition of H2O, and then subjected to celite filtration. Evaporation of the resultant mixture under diminished pressure gave a white solid. Recrystallization of this solid from chloroform/hexane gave a colorless needle-like crystal (1.346 g, 100%, m.p. 26 to 28° C.).
