Reaction Steps

Trifluoroacetic Acid (10 ml, 200 mmol) added to a mixture of Water (1 ml, 80 mmol) and 7-((3aS,4R,6R,6aR)-6-(((3-(2-(5-(tert-butyl)-1H-benzo[d]imidazol-2-yl)ethyl)cyclobutyl)(cyclobutyl)amino)methyl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-N-(2,4-dimethoxybenzyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (0.61 g, 0.80 mmol) at RT. The reaction was stirred o/n at RT and was quenched by the addition of Triethylsilane (0.26 ml, 1.6 mmol). The volatiles were removed in vacuo and resulting and the residue was taken up in MeOH (15 mls),500 mg K2CO3 and 8 drops of water were added and the reaction was stirred at RT for 1 hour. The mixture was filtered and the filter cake was washed with MeOH (10 ml). The filtrate was concentrated and the resulting residue purified by flash chromatogrpahy (DCM/7N NH3 in MeOH 90:10) to give the desired product (0.13 g) as a colorless foam.
