Versuchsvorschrift

A toluene solution containing 10 g of 2-methylbutyl 4'-hydroxybiphenyl-4-carboxylate and 3 g of pyridine was added dropwise to the above-described toluene solution of the acid chloride compound. After conclusion of dropping, the temperature was raised, and reaction was carried out for 8 hours at 50° C. After conclusion of the reaction, the product was washed with water and dried over magnesium sulfate, and the dried product was concentrated under reduced pressure. The residue was recrystallized from ethanol to obtain 8.2 g of the objective ester compound. (Yield: 45%)
