실험 절차

To a solution of 2-fluoroaniline (11.1 g, 100.0 mmol) in 100 ml of dry ether cooled in an ice bath is added ethyl chloroformate (7.1 ml, 8.1 g, 75.0 mmol). After addition, the mixture is allowed to warm to RT and is stirred at RT for 3 hours. Then a 10% sodium hydroxide solution (54 ml, 2.8M, 150.0 mmol) is added, followed by another 7.1 ml of ethyl chloroformate. The mixture is stirred at RT for 3 hours, and is then poured into water and ether. The organic layer is separated, washed with 5% HCl and with brine, and dried. The solvent is removed to give ethyl N-(2-fluorophenyl)carbamate.
