Reaction Conditions:
with acetic anhydride;iron in methanol at 85; for 1.5 h;
Steps:
150
A mixture of 4-methoxy-5-benzyloxy-2-nitrobenzamide (6.60 g, 21.9 mmol) and iron powder (8.14 g, 0.146 mol) in acetic acid/methanol (80 mL/80mL) was heated at 85+ 50C for 1.5 h. The reaction mixture was allowed to cool to RT and the iron was removed by filtration, and volatiles were removed in vacuo. The residue was taken up in sat. sodium bicarbonate and the mixture was extracted with ethyl acetate (600 mL x 3). The combined organic layers were washed with water (1x150 mL), brine (1x150 mL), dried (Na2SO4), filtered and concentrated in vacuo to give 4-methoxy-5-benzyloxy-2- aminobenzamide (5.2 g, 19.1 mmol, 87%). MS 273.2. (M+). HPLC retention time 4.585 min.
