実験手順

In a manner similar to that of Example 1b, by reaction of 600 mg (1 mmol) of ethyl 4′-(5-bromopentyloxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate with 850 mg (10.4 mmol) of ethylamine hydrochloride and 1.44 g (10.4 mmol) of potassium carbonate in 50 ml of ethanol. 350 mg of ethyl 4′-(5-ethylaminopentyloxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are obtained in the form of a colorless oil (yield=62%).
