Reaction Steps

To a solution of (2-bromo-5-methoxy-4-methyl-phenyl)-acetic acid (149.4 mg) in dichloromethane (1.8 mL) was added oxalyl chloride (0.055 mL) followed by DMF (1 drop) uder argon. Mixture was stirred at rt for 3 h. Mixture was concentrated to dryness. Dichloroethane (ca. 10 mL) was added, and the mixture was back concentrated to dryness to obtain crude (2-bromo-5-methoxy-4-methyl-phenyl)-acetic acid chloride (151 mg).
