실험 절차

To a suspension of 2-chloro-3-methylbenzoic acid (6.75 g, 39.39 mmol) [prepared as described above] in EtOAc were added a few drops of DMF and oxalyl chloride (5.1 ml, 1.5 eq.). After stirring the reaction mixture for 1.5 h, the solvent was removed in vacuo to give 2-chloro-3-methylbenzoyl chloride, which was used in the next step without further purification.
