実験手順

(2R)-2-[4-[4-(2,2,3,3-Tetrafluoropropoxy)phenyl]-4,5-dihydro-5-oxo-1H-1,2,4-triazol-1-yl]propanoic acid (1.0 g) and 2.5 ml of oxalyl chloride were added to 20 ml of dichloromethane, to which dimethylformamide (5 drops) was added dropwise at room temperature. After the reaction solution was stirred at room temperature for 2 hours, the solvent was distilled off under reduced pressure to give 1 g of (2R)-2-[4-[4-(2,2,3,3-tetrafluoropropoxy)phenyl]-4,5-dihydro-5-oxo-1H-1,2,4-triazol-1-yl]propanoyl chloride as a pale yellow oil. This product was used for the next step without purification.
