Procedure

(6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(3-fluoro-4-methoxyphenyl)-ethyl]amine [1.6 g, Intermediate (5)], 3-cyano-phenylboronic acid [1.5 g, Intermediate (6)], Cs2CO3 (8.3 g) and tetrakis(triphenylphosphine)palladium (45 mg) in a solution of water (8 mL) and ethylene glycol dimethyl ether (32 mL) is heated at 90° C. for 16 hours. The solution is poured into water and extracted twice with EtOAc (200 mL). The combined extracts are dried over sodium sulfate, filtered, and evaporated. The residue is subjected to chromatography on silica gel eluting with EtOAc to give 3-{6-[2-(3-fluoro-4-methoxy-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-benzonitrile [1.1 g, Example 1]. MS: 379 (M+H); 1H NMR (CDCl3): δ 8.3 (1H, s); 8.2 (1H, d (J=5.1 Hz)); 7.9 (1H, d (J=5.1 Hz)); 7.6 (1H, t); 7-7.2 (4H, m); 6.4 (1H, s); 5 (1H, m); 3.95 (3H, s); 3.8 (3H, s); 3.7 (2H, t); 3 (2H, t).
