Reaction Steps

A solution of 960 mg of the product of Stage F in 10 ml of methanol was hydrogenated for 12 hours at one atmosphere, then for 9 hours under 1.4 atmospheres in the presence of 150 mg of palladium on charcoal. After filtration, evaporation to dryness under reduced pressure was carried out. The residue was chromatographed on silica (eluant: ethyl acetate-cyclohexane (4-6)) to obtain 759 mg of the desired product.
