Reaction Steps

5-Bromo-pyridine-2-carboxylic acid (4-{2-[4-(4-fluoro-benzoyl)-piperidin-1-yl]-ethyl}-cyclohexyl)-amide (80 mg, 0.15 mmol) and 1-methylpiperazine (31 μl, 0.28 mmol) were dissolved in 2 ml dioxane. 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (9 mg, 0.016 mmol), cesium carbonate (76 mg, 0.23 mmol), water (1 μl, 0.078 mmol) and tri(dibenzylideneacetone)dipalladium chloroform complex (8 mg, 0.008 mmol) were added and the reaction mixture was stirred for 16 hrs at 110° C. The reaction mixture was then evaporated and purified by flash chromatography on silica gel (dichloromethane/methanol 100:0->90:10 gradient). The desired product was obtained as a light red solid (33 mg, 40%), MS: m/e=536.0 (M+H+).
