Participants

Reaction Steps

Distilled THF (10 mL) was added to 2-[4-(2-trimethylsilanylethoxymethoxy)-benzoyl]benzoic acid (1.86 g, 5 mmol) followed by thionyl chloride (0.43 mL, 6 mmol) and 3 drops of DMF. The system was stirred at room temperature under nitrogen for 2 h and monitored by TLC. The solvent was removed to give 3-chloro-3-[4-(2-trimethylsilanylethoxymethoxy)phenyl]-3H-isobenzofuran-1-one as a clear oil.
