To a solution of ethyl(2R)-2-[(2-[(2,3-Difluorobenzyl)thio]-6-([(4-ethylpiperazin-1-yl)sulfonyl]amino}pyrimidin-4-yl)oxy]propanoate (the product from step i) (0.72 g) in THF (10 ml) was added 2 M LiBH4 in TI-IF (1.3 ml). The reaction was then stirred for 18 h at RT. Saturated NH4Cl (150 ml) was then added to the reaction mixture which was extracted with DCM (3×150 ml). Organics were combined, dried (MgSO4) and reduced in vacuo and the resulting residue was purified by prep HPLC to give the title compound as a white solid.
