Reaction Steps

This compound is prepared from (1R,2S,3R,5S)-3-[2-((R)-3-amino-pyrrolidin-1-yl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-5-(4-hydroxymethyl-pyrazol-1-yl)-cyclopentane-1,2-diol. (Intermediate FB) using a procedure analogous to that of 1-((R)-1-{6-(2,2-diphenyl-ethylamino)-9-[(1R,2S,3R,4S)-4-(5-ethyl-tetrazol-2-yl)-2,3-dihydroxy-cyclopentyl]-9H-purin-2-yl}-pyrrolidin-3-yl)-3-pyridin-2-ylmethyl-urea hydrochloride (Example 113) by replacing 2-aminomethylpyridine with 4-aminomethylpyridine. MS (ES+) m/e 730.55 (MH+).
