Reaction Steps

5 g of 2,3,4-trimethoxy-5-methylphenol was dissolved in 10 ml of benzene and 10 g of silica alumina was added thereto. 1.8 g of 8-hydroxy-2,6-dimethyl-2,6-octadienoic acid dissolved in 4 ml of benzene was added to the above solution. The obtained solution was heated to 40° to 50° C. for two hours to allow reaction. The reaction mixture was then filtered and the precipitate was washed with ethyl ether while the filtrate was washed with water, dried over anhydrous magnesium sulfate and concentrated. The concentrate was purified by silica gel chromatography with the use of ether/n-hexane as the eluent to give 1.3 g of the title compound as a colorless oil.
