To a solution of 3-(dimethylamino) benzoic acid (5.0 g. 30.0 mmol) in dichloroethane (50 mL) was added oxalyl chloride (5.6 g, 44.6 mmol) drop wise followed by catalytic amount of DMF. The reaction was stirred for 16 h. The excess oxalyl chloride and solvent were removed under reduced pressure. The residue was chased with benzene to give the desired product (6.1 g, 92%).
