실험 절차
To a slurry of 2-amino-N-cyclopropyl-benzamide (6.7 g, 38.1 mmol) in water was added KHCO3 (9.5 g, 95.1 mmol) followed by careful addition of methylchloroformate (5.88 ml, 76.2 mmol). The mixture was stirred for 12 h then the aqueous layer was extracted with EtOAc. The EtOAc extract was washed with 1N HCl then dried over MgSO4 and concentrated to give 8.9 g (99%) of (2-cyclopropylcarbamoyl-phenyl)-carbamic acid methyl ester.
