実験手順

Oxalyl chloride (2 mL, 24 mmol) and DMF (0.4 mL) are added to a suspension of 3-methoxy-2-nitro benzoic acid (4 g, 20 mmol) in 200 mL of dichloromethane. The reaction mixture is stirred for 3 hours at 25° C. under nitrogen. The reaction solvents are removed under reduced pressure to yield 3-methoxy-2-nitrobenzoyl chloride (4.3 g, quant.) as a yellow solid. 1H NMR (DMSO): δ7.80 (1H, d, J=8 Hz), 7.65 (1H, t, J=9 Hz), 7.42 (1H, d, J=10 Hz).
