実験手順

330 mg of methyl (E,E,E)-7-[1-(1-methylethyl)-1,2,3,4-tetrahydroquinolin-6-yl]-3-methylocta-2,4,6-trienoate was dissolved in 10 ml of ethanol, followed by the addition of 1.0 ml of a 5N aqueous solution of sodium hydroxide. The obtained mixture was heated at 60° C. for one hour and adjusted to pH5 by adding 6N hydrochloric acid under cooling with ice. The crystals thus precipitated were recovered by filtration and recrystallized from ethanol to give 100 mg of the title compound as orange crystals.
