実験手順
A mixture of 3-(2,4-difluorophenylthio)-4-nitrobenzoic acid (1 g) and phosphorus pentachloride (0.7 g) in benzene (10 ml) was stirred at room temperature for 30 minutes. The mixture was concentrated under reduced pressure to give a powder of 3-(2,4-difluorophenylthio)-4-nitrobenzoyl chloride (1.2 g).
