Procedure
To a solution of 4-(cyclopropylmethoxy)-3-fluorobenzoic acid (1.57 g) in THF (50 mL) were added oxalyl dichloride (0.982 mL) and DMF (2 drops), and the mixture was stirred at room temperature for 30 min. The solvent was evaporated under reduced pressure to give 4-(cyclopropylmethoxy)-3-fluorobenzoyl chloride. This compound was used for the next reaction without further purification.
