実験手順

A mixture of (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(2-fluoro-4-trifluoromethyl-phenyl)-ethyl]-amine [800 mg, 2.29 mmol, see Example 52, step 1], (3-cyanomethyl-phenyl)-boronic acid, pinacol ester (563 mg, 3.43 mmol), and Cs2CO3 (1.86 g, 5.72 mmol) in ethylene glycol dimethyl ether (15 mL) and water (4 mL) is degassed by bubbling with Argon gas for 5 minutes, and treated with tetrakis(triphenylphosphine)palladium (0) (132 mg, 0.11 mmol) at room temperature. After 1 h at 85° C., the mixture is diluted with water (50 mL), and extracted with EtOAc (2×50 mL). The extracts are dried (MgSO4), filtered through a pad of SiO2, and concentrated to afford (3-{6-[2-(2-fluoro-4-trifluoromethyl-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-acetonitrile (1.2 g). LCMS: RT=2.47 minutes, 92% purity. MS: 431 (M+H).
