Participants

Reaction Steps

{(1S,2R,3S,4R)-4-[2-Chloro-6-(1-ethyl-propylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-propionyl-carbamic acid tert-butyl ester (300 mg, 0.59 mmol) is dissolved in DCM (5 mL). TFA (2 mL) is added and the reaction mixture is stirred at RT. The reaction is shown to be complete by LCMS after 1 hour. The solvent is removed in vacuo and the residue is partitioned between DCM (50 mL) and saturated NaHCO3 (50 mL). The organic layer is washed with water (20 mL) and brine (20 mL), dried over MgSO4, filtered and the solvent is removed in vacuo to give the title compound.
