Methanol → Methyl 2-chloro-3-nitrobenzoate

Participants

Reaction Steps

To the solution of 2-chloro-3-nitrobenzoic acid (1 g, 4.96 mmol), DMF (0.02 ml, 0.258 mmol) in DCM (20 mL) at 0° C. was added dropwise oxalyl chloride (0.478 ml, 5.46 mmol). The reaction was warmed to rt after the addition. After 3 h, methanol (10 mL) was added dropwise to the reaction mixture and the reaction was stirred at rt for 18 h and then the reaction was concentrated. The residue was dissolved in dichloromethane and passed through a plug of silica gel eluting with a 50% ethyl acetate/n-hexanes mixture. The filtrate was concentrated in vacuo to give the title compound as a white solid (1 g, 93% yield). MS (ESI) m/z: 216.0 (M+H)+.
