Reaction Steps

5% Palladium-carbon (0.2 g) was added to a solution of 1.970 g (5.0 mmole) of 9-(2,5-dimethoxy-3,4,6-trimethylphenyl)-9-phenyl-3-nonyn-1-ol in ethanol (20 ml), and catalytic reduction was conducted at room temperature for 2 hours. The catalyst was filtered out, and the ethanol was distilled off under reduced pressure. The residue was chromatographed on a silica gel column to perform purification (elution with isopropyl ether) to thereby give 1.97 g (99%) of 9-(2,5-dimethoxy-3,4,6-trimethylphenyl)-9-phenylnonanol. Its typical physical properties and nuclear magnetic resonance spectrum data are shown in Table 14.
