실험 절차
In a round bottom flask equipped with reflux condenser, N-(4-bromophenyl)-2-{[(3R)-1-(cyclopropylcarbonyl)-3-pyrrolidinyl]acetyl}hydrazinecarboxamide (1.896 mmol) in water (75 mL) was treated with potassium carbonate (9.48 mmol). The resulting slurry was stirred at reflux overnight (15 h). The heating was turned off and the reaction was allowed to cool to room temperature. The pH was adjusted to ˜4 using 6N aq HCl. The aqueous solution was concentrated in vacuo to ˜50 mL, which was then extracted with ethyl acetate. The combined organic phases were washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by flash chromatography (0-10% methanol/dichloromethane). The fractions were concentrated in vacuo to provide the title compound as an off-white amorphous solid (65%). MS(ES)+ m/e 391.1, 393.2 [M+H]+.
