Reaction Steps

A solution of (%)-cis-4-(2 amino-6-(cyclopropylmethylamino)-9H-purin-9-yl)-2-cyclopentene-1-methanol from Example 7 (0.30 g, 1 mmol), acetic anhydride (0.204 g, 2 mmol), N,N-dimethylaminopyridine (0.005 g, 0.04 mmol) in N,N-dimethylformamide (10 mL) was stirred at room temperature under nitrogen overnight. H2O (1 mL was added and the solution allowed to stir an additional hour, then concentrated under high vacuum. The residual oil was partitioned between saturated sodium bicarbonate solution (5 mL) and chloroform (3×50 mL). The combined chloroform extracts were dried (MgSO4), solvent evaporated and residue chromatographed on silica gel. Title compound was eluted with 4% methanol-chloroform; foamed from ethanol under high vacuum (0.330 g, 93%).
