To {3-{[tert-butyl(diphenyl)silyl]oxy}-1-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]cyclobutyl}acetonitrile (2.85 g, 4.30 mmol) in ethanol (120 mL) was added 5.0M sodium hydroxide in water (29 mL, 150 mmol). The reaction was stirred for 3 hours and diluted with water. The ethanol was removed under reduced pressure. The aqueous layer was extracted with ethyl acetate three times. The combine organic solutions were washed with brine, dried over Na2SO4, filtered and concentrated. The crude was purified with silica gel column eluting with a gradient from 0-10% MeOH/DCM to give of the product (1.62 g, 88%) as .off-white foam. LCMS (M+H)+: 425.2.
