Procedure

The title compound was prepared according to the procedure outlined in example 11 using a mixture of ethyl (2R)-2-[(2-[(2,3-difluorobenzyl)thio]-6-{[(1,2-dimethyl-1H-imidazol-4-yl)sulfonyl]amino}pyrimidin-4-yl)oxy]propanoate (the product from step (i) (0.25 g), lithium borohydride (2M solution in THF, 0.48 mL) and THF (6 mL). Purification was by reverse phase HPLC (symmetry as the stationary phase and TFA/acetonitrile as the mobile phase) then titurated with Toluene, DCM and then Et2O/iso-hexane to give the title compound as a white solid, 44 mg
