Participants

Reaction Steps

(2R) -2-[3-[4-(2,2,3,3-Tetrafluoropropoxy)phenyl]-2,3-dihydro-2-oxo-1H-imidazol-1-yl]propanoic acid (1.5 g) and 3.8 ml of oxalyl chloride were added to 30 ml of dichloromethane, to which dimethylformamide (7 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 1.5 g of (2R)-2-[3-[4-(2,2,3,3-tetrafluoropropoxy)phenyl]-2,3-dihydro-2-oxo-1H-imidazol-1-yl]propanoyl chloride as a pale yellow oil. This product was used for the next step without purification.
