Procedure

A mixture of 3-nitro-5-(trifluoromethyl)benzoic acid (2 g, 8.51 mmol) in DCM (30 mL) was added SOCl2 (1.242 mL, 17.01 mmol) at 20° C. The mixture was stirred at 20° C. for 2 h. TLC (PE/EA=2:1, Rf=0.3) showed the reaction was finished. The mixture was concentrated to give 3-nitro-5-(trifluoromethyl)benzoyl chloride (1.8 g, 6.50 mmol, 76% yield).
