Procedure

Potassium carbonate (0.265 g) was added to a solution of the product from step (ii) (0.44 g) and 4-fluorophenyl methyl sulfone (0.331 g) in NMP (20 ml) and the mixture heated at 120° C. for 16 h. The reaction was diluted with water and extracted with ethylacetate, the organics were dried and evaporated under reduced pressure. The residue was purified by reverse phase HPLC, yield 0.096 g.
