反応手順
To a suspension of 52.55 g (0.31 mol) of 4-chloro-3-methyl-benzoic acid in CH2Cl2 (1.2 L) with DMF (1 mL) at 0° C. under N2 with an outlet sparging through 2.5 N sodium hydroxide was added 29.56 mL (0.339 mol) of oxalyl chloride. The mixture was allowed to warm to room temperature over a 3 h period. The reaction mixture was concentrated and taken forward crude.
