Procedure

The title compound was prepared according to the procedure outlined in example 24 using a mixture of 2-[[2-[[(2,3-difluorophenyl)methyl]thio]-6-[(methylsulfonyl)amino]-4-pyrimidinyl]oxy]-(2R)-propanoic acid ethyl ester, (the product of step i) (0.28 g), THF (8 mL) and 2M lithium borohydride in THF (1.3 mL). Purification was by reverse phase HPLC (symmetry as the stationary phase and TFA/acetonitrile as the mobile phase). The resulting oil was triturated with toluene, DCM, then ether/iso-hexane to give the title compound as a white solid. Yield: 0.18 g
