Participants

Reaction Steps

2,3-dimethylbenzoic acid (35.0 g, 233 mmol) was heated to reflux temperature, in dry benzene (80 ml) containing thionyl chloride (45.0 g, 378 mmol) for five hours. The mixture was cooled, filtered and evaporated under reduced pressure to give 2,3-dimethylbenzoyl chloride (36.0 g, 92%) as an oil.
