Procedure

6-Chloro-N-cyclopropylmethylnicotinamide (Intermediate 1) (25 mg, 0.098 mmol) and N-[4-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-2-pyrrolidin-1-yl-isonicotinamide (Intermediate 18) (30 mg, 0.074 mmol), aqueous sodium carbonate (2N, 0.5 ml) and tetrakis(triphenylphosphine)palladium (4 mg) were heated at 80° C. in DMF (1 ml) for 18 hours. The reaction was absorbed onto silica, applied to a bond-elut (10 g, silica) and eluted with an ethylacetate/cyclohexane (0 to 100%), then acetone and methanol. The solvent was evaporated from the product fractions under vacuum and the residue triturated with ether to give N-(3-[5-(cyclopropylmethyl-carbamoyl)-pyridin-2-yl]-4-methyl-phenyl)-2-pyrrolidin-1-yl-isonicotinamide as a white solid (20 mg). LCMS: retention time 2.42 min, MH− 456.
