실험 절차

A mixture of (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(2-fluoro-4-trifluoromethyl-phenyl)-ethyl]-amine [1.47 g, 4.2 mmol, see Example 52, step 1], (3-hydroxy-phenyl)-boronic acid, (637 mg, 4.62 mmol), and Cs2CO3 (3.4 g, 10.5 mmol) in ethylene glycol dimethyl ether (20 mL) and water (4 mL) is degassed by bubbling with Argon gas for 5 minutes, and treated with tetrakis(triphenylphosphine)palladium(0) (243 mg, 0.21 mmol) at room temperature. After 15 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}-phenol (2 g). LCMS: RT=2.32 minutes; MS: 408 (M+H).
