Reaction Steps

This compound is prepared from carbonic acid (1S,4R)-4-(2,6-dichloro-purin-9-yl)-cyclopent-2-enyl ester ethyl ester (Intermediate AC) using a procedure analogous to that of (1R,2S,3R,5S)-3-[2-chloro-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-5-(5-ethyl-tetrazol-2-yl)-cyclopentane-1,2-diol (Intermediate BA6) by replacing 5-ethyl-2H-tetrazole with 4-ethyl-2H-[1,2,3]triazole (first step a).
