A solution of (5-Bromopyrazin-2-yl)-(6-trifluoromethyl-pyridin-3-yl)-amine (0.072 g) and {4-[4-(5-bromo-pyridin-2-yl)-phenyl]-cyclohexyl}-acetic acid methyl ester (0.087 g) in 2 Ml DME was charged with 2 M sodium carbonate (1 Ml) and Pd(PPh3)4 (0.027 g, 0.1 equiv). The biphasic mixture was sparged with nitrogen for 3 min, then stirred at 130° C. under microwave heating for 30 min. The reaction was partitioned between EtOAc and water, and the organic extracts were dried over magnesium sulphate and concentrated in vacuo. Purification by silica gel chromatography (33% EtOAc in hexanes) afforded the title compound: (M+H)+471.2.
