2.3 g of (5-cyclopropyl-2,4-dimethyl-phenyl)-acetic acid in 20 ml of dichloromethane were treated with 2.1 g of oxalyl chloride and a catalytic amount of dimethylformamide. The reaction mixture was stirred at room temperature for 2 hours. The solvent was removed in vacuo and the crude residue of (5-cyclopropyl-2,4-dimethyl-phenyl)-acetyl chloride (2.5 g) was used for the next step.
