Reaction Steps

The above mixture of 2-methanesulfonyl-4-(1-methyl-1H-pyrazol-4-yl)-pyrimidine and 2-methanesulfinyl-4-(1-methyl-1H-pyrazol-4-yl)-pyrimidine (1 g, 4.2 mmol), 4-amino-3-fluoro-phenol (1.1 g, 8.6 mmol) and K2CO3 (1.2 g, 8.6 mmol) in DMF (10 mL) was heated at 100° C. for 12 h. The reaction was partitioned between H2O and EtOAc (3×50 mL). The combined organics were dried (Na2SO4), concentrated in vacuo and chromatographed to provide 2-fluoro-5-(4-(1-methyl-1H-pyrazol-4-yl)pyrimidin-2-yloxy)benzenamine (402 mg). 1H NMR (400 MHz, DMSO-d6): δ 8.44 (d, J=5.2 Hz, 1H), 8.39 (s, 1H), 8.07 (s, 1H), 7.41 (d, J=5.2 Hz, 1H), 6.98 (t, J=9.6 Hz, 1H), 6.53 (dd, J=5.6, 2.0 Hz, 1H), 6.28 (d, J=8.4 Hz, 1H), 5.25 (br s, 2H), 3.88 (s, 3H). MS (ESI) m/z: 286.2 (M+H+).
