Methyl Methanesulfonate → Methyl 2-methoxy-4-(N-methylacetamido)-5-nitrobenzoate

Participants

Reaction Steps

A mixture of methyl 4-acetamido-2-methoxy-5-nitrobenzoate (2.0 g; 7.5 mmol), methyl methanesulfonate (0.85 g; 7.7 mmol) and K2CO3 (2.0 g; 14.5 mmol) in DMF (20 mL) was stirred for 36 h at rt. The mixture was thereafter poured into brine and extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated to give the crude sub-title compound.
