실험 절차

A solution of formic acid (106 mL) and acetic anhydride (53.0 mL) was stirred at room temperature for 1 h. Methyl 3-aminobenzoate (8.50 g, 56.2 mmol) was added and the resulting mixture was stirred overnight. The reaction mixture was then concentrated under reduced pressure to give a solid. The solid was dissolved in THF (50.0 mL) and this solution was cooled to 0° C. Borane dimethylsulfide (10.7 mL, 112 mmol) was added slowly and the resulting mixture was stirred at room temperature overnight. The reaction mixture was then cooled to 0° C. and MeOH (10 mL) was added slowly. This mixture was stirred for 3 hours and then concentrated under reduced pressure to give the title compound, which was used without any further purification.
