실험 절차

To a round bottom flask, 4-bromo-2,5-difluoroaniline (2 g, 9.62 mmol) and triphosgene (0.999 g, 3.37 mmol) were added under nitrogen and the mixture was cooled to −78° C. Dichloromethane (40 mL) was added followed by the slow addition of Hunig's base (3.36 mL, 19.23 mmol). The reaction was allowed to room temperature. Analysis by LCMS indicated desired intermediate formation. The solution was re-cooled to −78° C. and 2-[(3S)-1-(cyclopropylcarbonyl)-3-pyrrolidinyl]acetohydrazide (1.219 g, 5.77 mmol) in dichloromethane (10 mL) was added. The solution was allowed to warm to room temperature, and analysis by LCMS indicated desired product formation. After 2 h of stirring at room temperature the desired product began to precipitate out of solution and was collected by filtration and dried via vacuum filtration to afford the title product as a white solid (1340 mg, 62%). MS(ES)+ m/e 445.1, 446.9 M+H]+.
