실험 절차

To a stirred solution of methyl(4-formylaminophenyl)acetate (4.31 g) in THF (20.0 mL) at 0° C. was slowly added borane dimethylsulfide (8.61 mL, 90.8 mmol). The reaction mixture was stirred at room temperature overnight and then cooled to 0° C. MeOH (15 mL) was added cautiously and the resulting mixture was stirred for 3 h. The mixture was then concentrated under reduced pressure to give the title compound (4.0 g, 73% yield, 2 steps) as a clear oil.
