Reaction Conditions:
with dichlorosulfoxide;N,N-dimethyl-formamide for 4 h;Inert atmosphere;Reflux;
Steps:
To a solution of 2-methyl-5-nitrobenzoic acid (3.0 g, 16.6 mmol) in thionyl chloride (15 mL) kept under nitrogen atmosphere, was added N,N- dimethylformamide (1 drop). The mixture was heated to reflux for 4 h. The mixture was diluted with dichloromethane (20 mL) and concentrated to dryness to give a white solid (3.3 g, quantitative).
