実験手順

To a solution of 4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-2-(methylthio)pyrimidine from Example A18 (200 mg, 0.64 mmol) in dichloromethane was added m-CPBA (220 mg, 1.28 mmol). The reaction was stirred for 2 hour at RT. Water was added, the organic layer was separated and the aqueous layer was extracted with dichloromethane. The combined organics were washed with brine and concentrated in vacuo. The residue was combined with 5-amino-4-fluoro-2-methylphenol (180 mg, 1.28 mmol) and K2CO3 (176 mg, 1.28 mmol) in DMF (5 mL) and the resultant mixture was heated at 90° C. overnight. After filtration and concentration, the residue was purified by silica gel column chromatography to give 5-(4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)pyrimidin-2-yloxy)-2-fluoro-4-methylbenzenamine (210 mg, 84% yield). MS (ESI) m/z: 406.2 (M+H+).
