실험 절차
A solution comprising 9-[(1R,2S,3R,4S)-4-(tert-butoxycarbonyl-propionyl-amino)-2,3-dihydroxy-cyclopentyl]-6-(2,2-diphenyl-ethylamino)-9H-purine-2-carboxylic acid methyl ester (3.00 g, 4.66 mmol) in ethylenediamine (5 ml, 75 mmol) is heated at 90° C. for 1 hour. After cooling to room temperature, the ethylenediamine is removed in vacuo and purification by C-18 reverse phase column chromatography eluting with water (100%) followed by MeOH (100%) yields the title compound.
