Reaction Steps

This compound is prepared from 9-[(1R,2S,3R,4S)-2,3-dihydroxy-4-(4-hydroxymethyl-pyrazol-1-yl)-cyclopentyl]-6-(2,2-diphenyl-ethylamino)-9H-purine-2-carboxylic acid (2-amino-ethyl)-amide trifluoroacetate (first step a) using a procedure analogous to that of 1-{4-[9-[(1R,2S,3R,4S)-2,3-dihydroxy-4-(4-methyl-pyrazol-1-yl)-cyclopentyl]-6-(2,2-diphenyl-ethylamino)-9H-purin-2-ylamino]-cyclohexyl}-3-(3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-urea trifluoroacetate (Example 42) replacing N-[1-(2-pyridinyl)-4-piperidinyl]-1H-imidazole-1-carboxamide with imidazole-1-carboxylic acid ((R)-1-pyridin-2-yl-pyrrolidin-3-yl)-amide.
