Reaction Steps

A solution of (2-chloro-5-fluoropyrimidin-4-yl)-(2-fluorobenzyl)amine* (0.103 g, 0.40 mmol) in 5 mL of dry THF was treated with 4-fluorobenzylalcohol (0.062 g, 0.49 mmol) and a 1.0 M solution of KOtBu in tBuOH (0.4 mL, 0.4 mmol). The mixture was heated at 80° C. in a sealed vial for 18 h, partitioned between CH2Cl2 and water, and the organic phase was washed with brine, dried over Na2SO4, and filtered. The solvent was removed under reduced pressure and the residue purified by flash column chromatography (SiO2, 10→20% EtOAc/petroleum ether) to yield the title compound (0.157 g, 42%) as a white solid: mp 83-84° C.; 1H NMR (300 MHz, CDCl3) δ 7.83 (d, J=2.8, 1H), 7.45-7.27 (m, 5H), 7.15-6.96 (m, 5H), 5.37 (br s, 1H), 5.29 (s, 3H), 4.74 (d, J=5.9, 3H); MS (ESI) m/z 346 (M+H)+. *Singh, R.; Argade, A.; Payan, D. G.; Clough, J.; Keim, H.; Sylvain, C.; Li, H.; Bhamidipati, S., WO 2004014382 A1 20040219
