Cl.[N+:2]([C:5]1[CH:13]=[CH:12][CH:11]=[CH:10][C:6]=1[C:7]([NH2:9])=[O:8])([O-])=O.C(=O)([O-])[O-].[Na+].[Na+]>CO.[Fe]>[NH2:2][C:5]1[CH:13]=[CH:12][CH:11]=[CH:10][C:6]=1[C:7]([NH2:9])=[O:8]Concentrated hydrochloric acid (140μL) was added to a solution of the nitrobenzamide, V.3 (147 mg, 0.30 mmol) in methanol (2 ml). Iron (72 mg) was added and the reaction mixture was heated to 80° C. for 2 hours, before cooling. The reaction mixture was basified (saturated sodium carbonate solution), extracted into ethyl acetate, dried over magnesium sulphate and the solvent removed in vacuo to yield an off-white solid which was purified using flash chromatography(ethyl acetate) to yield the desired 2-aminobenzamide, VI.3 (47 mg, 34%).
