After N-alkylation of (X) with the protected bromomethylindazole (XI) to give (XII), acid hydrolysis of the acetonide yielded diol (XIII). In order to invert the undesired configuration at C4, the 4-hydroxyl group of (XIII) was selectively oxidized under Swern conditions to produce hydroxyketone (XIV). Subsequent reduction of (XIV) with ethanolic NaBH4 provided the required (4S,5R)-diol (XV). The silylethoxymethyl protecting group was finally removed with tetrabutylammonium fluoride in THF to afford the title compound.
