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-ethyl-[1,2,3]triazol-2-yl)-cyclopentane-1,2-diol. (Intermediate FC) using a procedure analogous to 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-aminomethyl pyridine with 4-aminomethylpyridine. MS (ES+) m/e 729.55 (MH+).
