Procedure

6-Chloro-N-[(R)-3,3-dimethyl-2-butyl]nicotinamide (Intermediate 11, 100 mg), {5-[(cyclopropylamino)carbonyl]-3-fluoro-2-methylphenyl}boronic acid (Intermediate 6, 100 mg), tetrakis(triphenylphosphine)palladium (10 mg) and aqueous sodium hydrogen carbonate (4 ml) were mixed in propan-2-ol (8 ml) and heated at 90° C. under nitrogen for 18 hrs. The solvents were evaporated from the cooled reaction under vacuum and the residue dissolved as far as possible in ethylacetate. The solution was applied to an SPE (SCX, 10 g) and washed with ethyl acetate. The product was eluted from the column with methanol/0.880 ammonia, and the solvents evaporated in vacuo. The residue was redissolved in ethyl acetate and filtered through an SPE (silica, 0.5 g). The filtrate was reduced to dryness under vacuum and triturated with ether to give 6-{5-[(cyclopropylamino)carbonyl]-3-fluoro-2-methylphenyl}-N-[(1R)-1,2,2-trimethylpropyl]-3-pyridinecarboxamide.
