HCID 226083993-Nitro-5-(trifluoromethyl)benzoyl chloride

Procedure

A solution of thionyl chloride (30 ml) and 3-nitro-5-(trifluoromethyl)benzoic acid (10 g) was heated to reflux for 2 h. The reaction mixture was concentrated under reduced pressure and treated with toluene (10 ml) which was then removed under reduced pressure to afford 3-nitro-5-(trifluoromethyl)benzoyl chloride.
