A solution of tert-butyl 4-{[(2-[(2,3-difluorobenzyl)thio]-6-((1R)-1-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]ethoxy}pyrimidin-4-yl)amino]sulfonyl)piperazine-1-carboxylate (the product of step i) (0.23 g) in 10% trifluoroacetic acid/DCM (5 mL) was stirred at room temperature for 1 h. The mixture was evaporated to dryness in vacuo. The resulting crude oil was purified by reverse phase HPLC (75% to 5% gradient of 0.1% aqueous ammonium acetate in acetonitrile as eluent) to give the title compound as a white solid, Yield: 40 mg.
