Procedure

To a solution of N-[(1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]oxy}methyl)cyclopentyl]-N′-[(1R,2S)-2-methoxy-2,3-dihydro-1H-inden-1-yl]pyrimidine-4,6-diamine (0.188 g, 0.314 mmol) in THF (1.70 mL) and H2O (1.70 mL) was added AcOH (5.08 mL). The solution was stirred overnight then concentrated in vacuo and purified by flash chromatography (0 to 5% MeOH/EtOAc) to obtain the title compound (0.112 g, 74%). LC/MS: Rt=1.46 min, ES+ 485 (Formic Acid).
