A mixture of 1-[9-((1R,2S,3R,4S)-2,3-dihydroxy-4-propionylamino-cyclopentyl)-6-(2,2-diphenyl-ethylamino)-9H-purin-2-yl]-1H-pyrazole-4-carboxylic acid ethyl ester (0.07 g, 0.112 mmol) and 40% aqueous methyl amine solution (3 ml) is heated to 65° C. for 12 h. The reaction mixture is concentrated in vacuo and purification of the crude residue by chromatography on silica eluting with 4% methanol in chloroform yields the title compound.
