実験手順
A mixture of 4,7-dihydro-4,7-dioxo-1-(2-propynyl)-6-(2-propynyloxy)-1H-cyclohepta[b]pyridine-2-carboxylic acid ethyl ester (20 g, described in Example 20), 5% palladium on charcoal (2.0 g) and acetic acid (400 ml) is stirred rapidly under an atmosphere of hydrogen until 5.7 liters of hydrogen are absorbed. The mixture is filtered and the filtrate is evaporated. The residue is subjected to chromatography on silica gel using acetone-hexane (1:1). The eluates are evaporated to give a residue of the title compound.
