실험 절차

7-[(1R,3S,4S)-3-[tert-butyl(dimethyl)silyl]oxy-4-([tert-butyl(dimethyl)silyl]-oxymethyl)cyclopentyl]-N-[(1S)-2,3-dihydro-1H-inden-1-yl]-7H-pyrrolo[2,3-d]pyrimidin-4-amine (1.66 g, 0.00280 mol) was dissolved in a mixture of tetrahydrofuran (6.6 mL), water (6.6 mL, 0.36 mol), and acetic acid (19 mL, 0.34 mol). The solution was then heated to 40° C. overnight. The mixture was then cooled and evaporated, azeotroped with toluene (2×50 mL) and the residue was purified by silica gel chromatography eluting with 0 to 100% ethyl acetate in dichloromethane to yield the product as a white solid, 1.05 g (74%). LC/MS: Rt=1.68 min, ES+ 479 (AA standard).
