실험 절차

A vigorously-stirred, 0° C. solution of (3S)-2-oxo-3-(benzoylamino)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepine-1-acetic acid benzyl ester (600b) (461 mg, 1.07 mmol, in THF (5 ml) and sat. aq. NaHCO3 (2.5 ml) was treated with a THF solution (0.35 ml) of methyl chloroformate (151 mg, 1.6 mmol) and the reaction was stirred for 45 min at RT. The reaction was poured onto CH2Cl2 and washed with H2O, dried over Na2SO4 and concentrated in vacuo. Chromatography (flash, SiO2, 0% to 10% MeOH/CH2Cl2) gave 525 mg of 602j as a white solid.
