실험 절차

To a round-bottom flask was added 4-bromo-1-isocyanato-2-(trifluoromethyl)benzene (0.4 mL, 2.55 mmol) and dichloromethane (10 mL) under nitrogen. The mixture was cooled to −78° C. and a solution of 2-[(3S)-1-(cyclopropylcarbonyl)-3-pyrrolidinyl]acetohydrazide (520 mg, 2.461 mmol) in dichloromethane (15 mL) was then added to the cooled solution and immediately allowed to warm to room temperature. After 1 h, analysis by LCMS indicated desired product formation. The resulting precipitate was collected and dried under vacuum filtration to yield the title product as a white solid (130 mg, 88%). MS(ES)+ m/e 476.9, 478.9 M+H]+.
