Thionyl Chloride → 2-(3-Fluoro-4-methoxy-phenyl)-cyclopropanecarbonyl chloride

Participants

Reaction Steps

After 2-(3-fluoro-4-methoxy-phenyl)-cyclopropane carboxylic acid (0.848 g, 4.03 mmol) obtained in Step A was dissolved in anhydrous MC (10 mL), SOCl2 (3 mL, 40.34 mmol) was added thereto, and the mixture was stirred at room temperature for 18 hours. After the termination of the reaction, the reactant was concentrated under reduced pressure to obtain the title compound, which was used in the next step without a separate purification process
