(3R)-pyrrolidin-3-amine → (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 trifluoroacetate

Participants

Reaction Steps

This compound is prepared from (1R,2S,3R,5S)-3-[2-chloro-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-5-(4-hydroxymethyl-pyrazol-1-yl)-cyclopentane-1,2-diol (Intermediate BA7) using a procedure analogous to that of (1R,2S,3R,5S)-3-[6-(2,2-diphenyl-ethylamino)-2-(2-piperidin-1-yl-ethylamino)-purin-9-yl]-5-(4-hydroxymethyl-pyrazol-1-yl)-cyclopentane-1,2-diol trifluoroacetate (Example 46) replacing the 1-(2-aminoethyl)piperidine with (3R)-(+)-3-amino pyrrolidine. MS (ES+) m/e 596 (MH+).
