Procedure

6-Chloro-N-cyclopropylmethylnicotinamide (Intermediate 1) (18.5 mg, 0.073 mmol) and 4-methyl-N-(3-pyridin-2-yl-phenyl)-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (Intermediate 6) (30 mg, 0.072 mmol), aqueous sodium carbonate (2N, 0.5 ml) and tetrakis(triphenylphosphine)palladium (4 mg) were heated at 90° C. in DMF (1 ml) for 4 hours. The reaction was absorbed onto silica, applied to a bond-elut (5 g, silica) and eluted with an ethylacetate/cyclohexane (0 to 100%) and then acetone. The solvent was evaporated from the product fractions under vacuum and the residue triturated with ether to give N-cyclopropylmethyl-6-[2-methyl-5-(3-pyridin-2-yl-phenylcarbamoyl)-phenyl]-nicotinamide as a white solid (20 mg). LCMS: retention time 3.18 min, MH+ 463. NMR: δH [2H6]-DMSO 10.43,(1H, s), 9.14,(1H, s), 8.86,(1H, t), 8.69,(1H, s), 8.53,(1H, s), 8.34,(1H, d), 8.11,(1H, s), 8.01,(1H, d), 7.95–7.89,(3H, m), 7.81–7.78,(2H, m), 7.53–7.46, (2H, m), 7.38,(1H, t), 3.21,(2H, t), 2.44,(3H, s), 1.07,(1H, m), 0.47,(2H, m), 0.27,(2H, m).
