Reaction Steps

A solution of (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(4-trifluoromethoxyphenyl)-ethyl]amine (1.6 g), 2-[2-fluoro-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-2-methyl-propionic acid methyl ester (0.63 g), Cs2CO3 (11.6 g) and tetrakis(triphenylphosphine)palladium (0) (33 mg) in water (8 mL) and DME (32 mL) is heated at 90° C. for 16 hours. The solution is poured into water and extracted with EtOAc (2×200 mL). The combined extract is dried over sodium sulfate, filtered, evaporated in vacuo and chromatographed on silica gel eluting with EtOAc to afford 2-(2-fluoro-5-{2-methoxy-6-[2-(4-trifluoromethoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid methyl ester (300 mg). MS: 508 (M+H); 1H NMR (300 MHz, CD3OD) □7.8, (d, 1H, J=0.3 Hz); 7.7 (m, 1H); 7.4 (d, 2H, J=0.4 Hz); 7.2-7.3 (m, 4H); 6.6 (s, 1H); 4.2 (s, 3H); 4 (s, 3H); 3.9 (m, 2H); 3.05 (t, 2H); 1.65 (s, 6H).
