To a magnetically stirred mixture of 3-(4-amino-5-fluoropyrimidin-2-yloxymethyl)-benzonitrile (0.075 g, 0.31 mmol) and 2-fluorobenzylisocyanate (0.59 mL, 0.46 mmol) in dry DMF (1.5 mL) was added LiHMDS (1.0 M in THF, 0.31 ml, 0.30 mmol). The vial was capped and the mixture stirred at room temperature for 8 h. Saturated aq. NH4Cl (3 ml) was added and the mixture was stirred for 4 h. The heterogeneous mixture was filtered, and the solid was washed with hot water, washed with E2O, and then dried under vacuum to give the title compound (0.075 g, 62%) as a white solid: mp 177-178° C.; 1H NMR (400 MHz, DMSO-d6) δ 10.04 (s, 1H), 8.90 (t, J=5.7 Hz, 1H), 8.37 (d, J=2.8 Hz, 1H), 7.85 (br s, 1H), 7.80 (d, J=7.5 Hz, 1H), 7.74 (d, J=8.0 Hz, 1H), 7.60 (t, J=7.8 Hz, 1H), 7.42-7.38 (m, 1H), 7.35-7.29 (m, 1H), 7.20-7.14 (m, 2H), 5.33 (s, 2H), 4.49 (d, J=5.8 Hz, 2H); HPLC-MS (ESI) m/z 396.3 (M+H)+, 394.3 (M−H)−.
