Participants

Reaction Steps

A solution of 4-methoxy-5-(4-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyri-dine-2-yl)-2-(methylthio)pyrimidine (0.28 g, 0.67 mmol) in DCM (10 mL) was treated with mCPBA (0.20 g, 0.80 mmol), stirred at RT for 3 h, treated with pyrrolidine (0.50 mL, 6.1 mmol) and stirred at RT overnight. The mixture was treated with satd. NaHCO3, extracted with DCM (3×) and the combined organics were dried over MgSO4, concentrated to dryness and purified by silica gel chromatography (MeOH/DCM) to afford 4-methoxy-5-(4-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(pyrrolidin-1-yl)pyrimidine (0.19 g, 64%). 1H NMR (400 MHz, DMSO-d6): δ 8.76 (s, 1H), 8.37 (s, 1H), 8.35 (d, J=5.7 Hz, 1H), 8.27 (s, 1H), 7.97 (s, 1H), 7.85 (s, 1H), 7.25 (d, J=2.4 Hz, 1H), 6.60 (dd, J=5.7, 2.5 Hz, 1H), 4.00 (s, 3H), 3.84 (s, 3H), 3.55 (s, 5H), 2.18 (s, 3H), 1.93-1.92 (m, 4H); MS (ESI) m/z: 444.2 (M+H+).
