Reaction Steps

To a solution of 2,3,5-trifluoro-N-(2-fluoro-4-iodophenyl)-6-nitrobenzenamine (Intermediate 12. 700 mg, 1.7 mmol) in THF (20 mL) was added NaOMe solution at −78° C. (which was prepared by dissolving Na metal (39 mg, 1.7 mmol) in 4 mL of methanol). The reaction mixture was brought to rt and stirred for 1 h at same temperature. The progress of reaction was monitored by TLC. After completion, the reaction mixture was quenched with water and extracted with ether. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by flash column chromatography to yield 2,5-difluoro-N-(2-fluoro-4-iodophenyl)-3-methoxy-6-nitrobenzenamine as yellow solid (597 mg). 1H-NMR (400 MHz, CDCl3): δ 3.95 (3H, s), 6.51-6.56 (1H, m), 6.57-6.65 (1H, m), 7.34 (1H, d, J=8.8), 7.42 (1H, dd, J=1.6, 10), 7.7 (1H, s).
