Reaction Steps

Fe powder (3.4 g, 60 mmol) was added to a mixture of methyl 4-methylamino-3-nitrobenzoate (2.5 g, 12.0 mmol), AcOH (10 mL) and MeOH (100 mL) at reflux. The mixture was heated at reflux for 30 min and allowed to cool to rt. The pH was adjusted to ˜8 by addition of NaHCO3 (aq, sat) and the mixture was filtered through Celite. The filter cake was washed with EtOH and the combined filtrates were concentrated and the residue extracted with EtOAc. The combined extracts were washed with brine, dried and concentrated to give the sub-title compound. Yield: 1.91 g (88%)
