실험 절차
THF (25 mL) was added to 2-(4-chlorobenzoyl)benzoic acid (1 g, 3.8 mmol) followed by thionyl chloride (0.55 mL, 7.6 mmol) and a catalytic amount of DMF (3 drops). The system was stirred under nitrogen for 4 h at room temperature and monitored by TLC. Removal of the solvent gave 3-chloro-3-(4-chlorophenyl)-3H-isobenzofuran-1-one as a colourless oil (1.06 g, 3.8 mmol, 100%).
