実験手順

2-(4-Chloro-2-fluorophenyl)acetic acid (25.0 g, 133 mmol) was dissolved in MeOH (133 mL). Sulfuryl dichloride (9.67 mL, 133 mmol) was then added, and the reaction was stirred at ambient temperature for 3 hours. The reaction mixture was concentrated in vacuo to give the title compound which was used without further purification. MS (m/z)=203 (M+H)+.
