Procedure
5-Bromo-N-((1R,2R)-2-hydroxy-cyclohexyl)-6-(2,2,2-trifluoro-ethoxy)-nicotinamide (59.8 g, 151 mmol) was dissolved in toluene (2500 mL) and DMF (200 mL). To this solution was added with stirring [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II) CH2Cl2 (6.15 g, 7.5 mmol), 3,4-dichlorophenylboronic acid (30.2 g, 158 mmol) and sodium carbonate solution (2M, 150 mL). This mixture was heated to 90° C. for 2 h, cooled to room temperature and filtered through diatomaceous earth. The filter cake was thoroughly washed with ethyl acetate (3000 mL). The filtrates were combined, washed twice with water (2×2000 mL), and the water phases were extracted with ethyl acetate (2×1500 mL). Organic phases were pooled, dried with MgSO4 and the volatiles removed in vacuo. The residue was purified by filtration through silica (500 g) with ethyl acetate. The solvent was removed and the residue was triturated with diethyl ether to give after drying in vacuo the title compound (45.6 g) as a grayish solid; MS 463.079, 465.077 (M+H)+.
