Procedure

6-Chloro-N-cyclopropylmethylnicotinamide (Intermediate 1)(25.5 mg, 0.10 mmol) and N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (Intermediate 8)(30 mg, 0.110 mmol), aqueous sodium carbonate (2N, 0.5 ml) and tetralkis(triphenylphosphine)palladium (4 mg) were heated at 90° C. in DMF (1 ml) for 3 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 6-(5-cyclopropylcarbamoyl-2-methyl-phenyl)-N-cyclopropylmethyl-nicotinamide as a cream solid. LCMS: retention time 2.70 min, MH+ 350. NMR: δH [2H6]-DMSO 9.11,(1H, s), 8.84,(1H, t), 8.48,(1H, d), 8.31,(1H, dd), 7.88,(1H, s), 7.81,(1H, d), 7.70,(1H, d), 7.41,(1H, d), 3.20,(1H, t), 2.86,(1H, m), 2.37,(3H, s), 1.06,(1H, m), 0.69,(2H, m), 0.57,(2H, m), 0.46,(2H, m), 0.26, (2H, m).
