Procedure

The title compound was prepared according to the procedure outlined in example 24 using 2-[[6-[(1-azetidinylsulfonyl)amino]-2-[[(2,3-difluorophenyl)methyl]thio]-4-pyrimidinyl]oxy]-(2S)-propanoic acid, ethyl ester, (the product of step ii) (0.28 g), THF (8 mL) and 2M lithium borohydride in THF (0.57 mL). Purification was by column chromatography on silica using EtOAc/isohexane (2:3) as eluent to give the title compound as a white solid. Yield: 0.15 g
