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, 0.10 mmol), aqueous sodium carbonate (2N, 0.5 ml) and tetrakis(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.
