実験手順
To a suspension of LiAlH4 (1.707 g, 0.045 mol) in anhydrous diethyl ether (80 mL) in a 3-necked rb flask equipped with addition funnel at 0° C. in an ice-water bath was added dropwise a solution of 3-tert-butoxy-benzoic acid ethyl ester (5.0 g, 0.0225 mol) in ether (20 mL). The reaction mixture was left to warm to rt over 15 min, then cooled in an ice-water bath and quenched by dropwise addition of H2O. The mixture was partitioned between ether and H2O, the aqueous layer washed with ether (2×30 mL), the organics combined, washed with brine, dried (MgSO4), filtered and concentrated to give 3.70 g (82%) of the title compound.
