Procedure
To a solution of 2-(methylthio)-4-(1H-pyrazol-4-yl)pyrimidine (200 mg, 1 mmol) in dichloromethane (3 mL) and H2O (1 mL) was added 4-methoxybenzylchloride (200 mg, 1.28 mmol) at 0° C. The mixture was stirred at RT overnight. The organic layer was separated, washed with brine and concentrated in vacuo to give crude 4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-2-(methylthio)pyrimidine. 1H NMR (300 MHz, DMSO-d6) δ 8.58 (s, 1H), 8.50, (d, J=5.4 Hz, 1H), 8.16 (s, 1H), 7.40 (d, J=5.4 Hz, 1H), 7.27 (d, J=8.4 Hz, 2H), 7.22 (d, J=8.4 Hz, 2H), 5.30 (s, 2H), 3.72 (s, 3H), 2.51 (s, 3H); MS (ESI) m/z: 313 (M+H+).
