Reaction Steps

To a solution of 3-[2,6-dioxo-1,3-dipropyl-7-(tetrahydropyran-2-yl)-2,3,6,7-tetrahydro-1H-purin-8-yl]-3-hydroxy-8-oxa-bicyclo[3.2.1]octane-6,7-dicarboxylic acid dimethyl ester (0.060 mmol, 0.030 g) in 1:1 THF/MeOH (6 ml) was added 1N HCl (3 drops). The reaction was stirred at room temperature 3d and then concentrated to dryness. The residue was purified by PLC on a 1 mm layer, eluting with 20% THF/CH2Cl2, providing the title compound (0.0162 g, 56%). 13C NMR (100 MHz, CDCl3): 11.53 (q), 11.50 (q), 21.72 (t), 21.75 (t), 41.74 (t), 43.82 (t), 45.85 (t), 51.02 (d), 52.64 (q), 70.37 (s), 77.12 (d), 107.53 (s), 149.12 (s), 151.17 (s), 156.32 (s), 159.98 (s), 173.36 (s).
