Reaction Steps

210 mg (0.45 mmol) of (1S*,3S*,3aR*,8bS*)-6-(2-azidoethoxy)-3a-(4-chlorophenyl)-3-phenyl-2,3,3a,8b-tetrahydrocyclopenta[b]benzofuran-1,8b-(1H)-diol (Example 49A) are dissolved in 34 ml of ethanol. Addition of 56 mg of 10% palladium on activated carbon is followed by stirring at RT under hydrogen at atmospheric pressure for 15 minutes. The residue from filtration and concentration is filtered through silica gel 60. Toluene is used for washing, and a 1:1 dichloromethane/ethanol mixture is used for elution. Concentration results in 179 mg (90% of theory) of the product, which is finally purified by Method 23A.
