Procedure

A mixture of 4-acetylamino-2-methoxy-5-nitro-benzoic acid methyl ester (4.0 g, 14.9 mmol), methanesulfonic acid methyl ester (1.3 mL, 15.4 mmol) and K2CO3 (4.0 g, 28.9 mmol) in 40 mL DMF was stirred overnight at ambient temperature. The mixture was poured onto ice water and diluted with dichloromethane. The organic phase was separated, dried and concentrated i. vac.
