Procedure

To 3-(methyl(2-morpholinoethyl)carbamoyl)benzoic acid (1.37 g, 4.69 mmol, 1.00 equiv) in dichloromethane (17 mL) was added 2 drops of N,N-dimethylformamide followed by the addition of oxalyl dichloride (3.63 g, 28.14 mmol, 6.00 equiv). The resulting solution was stirred for 1 h at 50° C. in an oil bath then concentrated under vacuum to afford 1.41 g (87%) of 3-(methyl(2-morpholinoethyl)carbamoyl)benzoyl chloride as a gray-yellow solid.
