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-2-methyl-propyl)-amide (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).
