To a suspension of 4-(2-oxopyrrolidin-1-yl)benzoic acid (19.94 mg, 0.097 mmol) in DCM (5 ml) was added oxalyl chloride (2M solution in DCM, 0.058 ml, 0.117 mmol) and 2 drops of DMF. The resulting mixture was stirred at r.t for 1 hr., then concentrated in vacuo. The residue (off white solid) was used in subsequent reactions without further purification.
