反応手順

To a dimethylformamide solution (30 ml) of 6-(10-hydroxydecyl)-2,3-dimethoxy-5-methylphenol (1.6 g) are added bis(3-methoxysalicylidene)ethylenediiminocobalt(II) (0.06 g) and pyridine (10 mg), and the mixture is stirred in air streams at atmospheric temperature and pressure for 72 hours. After the reaction has been completed, the reaction product is isolated in the same manner as described in Example 7. The crude crystals thus obtained are recrystallized from ether-hexane (1:3). The above procedure yields 6-(10-hydroxydecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (1.1 g) as orange-yellow needles melting at 51° C.-53° C.
