実験手順
A solution of 5-(4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)pyrimidin-2-yloxy)-2-fluoro-4-methylbenzenamine (0.5 g, 1.2 mmol) in dichloromethane (20 mL) was treated with TFA (5 mL) at 0° C. The mixture was then stirred at RT for 12 h. The solvent was removed in vacuo, the residue was washed with ether and treated with saturated ammonia solution. The solid was collected via filtration and dried under vacuum to give 5-(4-(1H-pyrazol-4-yl)pyrimidin-2-yloxy)-2-fluoro-4-methylbenzenamine (240 mg, 68%, yield). 1H NMR (400 MHz, MeOD): δ 8.41 (d, J=5.2 Hz, 1H), 8.21 (br s, 2H), 7.40 (d, J=5.2, 1H), 6.90 (d, J=11.6 Hz, 1H), 6.62 (d, J=8.0 Hz, 1H), 1.99 (s, 3H). MS (ESI) m/z: 286.1 (M+H+).
