実験手順
To a solution of methyl 4-(methylamino)benzoate (2.0 g, 12.1 mmol) in THF (30 mL) was added LAH (6.1 mL, 2.4 M in THF, 14.5 mmol) at 0° C. The reaction was stirred at r.t. for 2 h. The reaction was quenched with EtOAc (50 mL) and water (2 mL). The mixture was dried (Na2SO4) and concentrated. Purification by silica gel chromatography (PE:EtOAc=3:1) gave 1.0 g (60%) of the title compound as a yellow oil. [M+H] Calc'd for C8H11NO, 138. Found 138.
