실험 절차

Argon is bubbled through a mixture of benzo[b]thiophen-2-ylmethyl-(6-chloro-2-methyl-pyrimidin-4-yl)-amine [247 mg, 0.81 mmol], 3-(1-carboxy-1-methyl-ethyl)-phenyl boronic acid [304 mg, 1.46 mmol, see Example 49(b) step 2], Cs2CO3 (792 mg, 2.43 mmol), and tetrakis(triphenylphosphine)palladium (0) (92 mg, 0.08 mmol) in ethylene glycol dimethyl ether (2.5 mL) and water (0.5 mL), for a period of 10 minutes. The reaction vessel is sealed and heated to 90° C. After stirring for 6 hours the heating is turned off and the mixture is allowed to cool to ambient temperature upon standing for 24 hours. The mixture is diluted with water (20 mL) and extracted twice with EtOAc (30 mL). The organic extracts are combined and dried over magnesium sulfate, filtered and concentrated to afford 2-(3-{6-[(benzo[b]thiophen-2-ylmethyl)-amino]-2-methyl-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid [51.6 mg, 14.7%, Example 72] as a solid. LCMS RT=2.27 minutes, MS: 434 (M+H).
