Reaction Steps

A mixture of N-(3-fluoro-4-hydroxyphenyl)acetamide (Compound A of Example 13, 1.33 g, 7.87 mmol), 2-chloro-4-nitropyridine (Aldrich, 1.24 g, 7.87 mmol), K2CO3 (1.6 g, 11.8 mmol), and DMF (25 mL) was heated at 100° C. for 9 h. The mixture was concentrated in vacuo and the residue was partitioned between EtOAc and saturated aq. NaHCO3 solution. The EtOAc phase was washed with brine, dried (MgSO4), and concentrated in vacuo. The residue was purified by flash column chromatography on SiO2 eluting with 30-80% EtOAc in hexanes to give the title compound (1.6 g, 73%) as a pale yellow solid. 1H NMR (DMSO-d6) δ 10.25 (s, 1H), 8.35 (d, 1H, J=7 Hz), 7.80 (d, 1H, J=14 Hz), 7.50 (d, 1H, J=3 Hz), 7.33 (m, 2H), 7.02 (m, 1H), 2.06 (s, 3H); MS (ESI+): m/z 281.16 (M+H)+.
