실험 절차

In a manner similar to that of Example 2a, by reaction of 270 mg (6.75 mmol) of sodium hydroxide with 340 mg (0.66 mmol) of ethyl 4′-(3-cyclopropylaminoethoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate (Example 19b) in 30 ml of tetrahydrofuran. 240 mg of 4′-(3-cyclopropylaminoethoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylic acid are obtained in the form of a white solid (m.p.=233° C., yield=75%).
