Procedure

The title compound was prepared according to the procedure outlined in example 24 using 2-[[6-[(cyclopropylsulfonyl)amino]-2-[[(2,3-difluorophenyl)methyl]thio]-4-pyrimidinyl]oxy]-(2R)-propanoic acid ethyl ester, (the product of step i) (0.30 g), THF (8 mL) and 2 M lithium borohydride in THF (2 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 methanol, toluene, DCM, then ether/iso-hexane to give the title compound as a white solid. Yield: 0.20 g
