Procedure

To a solution of 1-{[(2S,1R,4R,5R)-4-(6-chloropurin-9-yl)-7,7-dimethyl-3,6,8-trioxabicyclo[3.3.0]oct-2-yl]methylthio}-2-fluorobenzene, a compound of formula (3), (0.125 g, 2.86 mmoles) in 10 mL of ethanol and 1 mL of triethylamine was added cyclopentylamine in excess, and the mixture refluxed under nitrogen for 24 hours. The solvent was removed under reduced pressure, and the residue was purified by preparative TLC using 1:1 EtOAc:Hexanes to give (9-{(4S,1R,2R,5R)-4-[(2-fluorophenylthio)methyl]-7,7-dimethyl-3,6,8-trioxabicyclo[3.3.0]oct-2-yl}purin-6-yl)cyclopentylamine, a compound of formula (4), as a yellow oil (80 mg, 56%)
