Reaction Steps
The title compound was prepared according to the procedure outlined in example 24 using 2-[[2-[[(2,3-difluorophenyl)methyl]thio]-6-[[(1-methyl-1H-imidazol-4-yl)sulfonyl]amino]-4-pyrimidinyl]oxy]-(2R)-propanoic acid ethyl ester (the product of step i) (0.28 g), THF (8 mL) and 2 M lithium borohydride in THF (0.81 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, methanol, then ether/iso-hexane to give the title compound as a white solid. Yield: 0.12 g
