Reaction Steps

The title compound is prepared analogously to (R)-2-benzyloxy-N-((1S,2R,3S,4R)-4-{6-(2,2-diphenyl-ethylamino)-2-[(R)-3-(3-pyridin-3-yl-ureido)-pyrrolidin-1-yl]purin-9-yl}-2,3-dihydroxy-cyclopentyl)-propionamide (Example 181, step 5), by substituting N-{(1S,2R,3S,4R)-4-[2-(4-amino-pyrazol-1-yl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-2-hydroxy-acetamide (Intermediate ZP) for (R)—N-{(1S,2R,3S,4R)-4-[2-((R)-3-amino-pyrrolidin-1-yl)-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-2-benzyloxy-propionamide (Example 181, step 4).
