Reaction Steps

To a degassed mixture of N-cyclopropyl-3-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.1 g) [prepared as described in WO 06110173], the product of step ii) (0.09 g) and potassium carbonate (0.06 g) in DMF (5 mL) under nitrogen, was added tetrakis(triphenylphosphine)palladium(0) (0.02 g) and the mixture stirred at 80° C. for 16 hours. The reaction mixture was concentrated to dryness and the crude product was purified (SiO2, elution with 90:10:0.1 dichloromethane: methanol: triethylamine) and by HPLC. The fractions containing product were concentrated to dryness and the residue crystallised from acetonitrile to afford the title compound as a solid (0.04 g).
