Reaction Steps

A mixture of methyl 9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)-tetrahydro-2-furanyl]-6-[(2,2-diphenylethyl)amino]-9H-purine-2-carboxylate (Preparation 18) (92 mg, 0.18 mmol) and N-(2-aminoethyl)morpholine (0.25 ml, 1.9 mmol) were heated at 120° C. under a nitrogen atmosphere for 75 minutes. The reaction mixture was allowed to cool to room temperature and diethyl ether (2 ml) added to precipitate the title compound as a white solid which was filtered off and dried (68 mg).
