Sodium Hydroxide → 4'-(3-Propylaminopropoxy)-3'-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylic acid

Participants

Reaction Steps

In a manner similar to that of Example 2a, by reaction of 584 mg (14.6 mmol) of sodium hydroxide with 770 mg (1.46 mmol) of ethyl 4′-(3-propylaminopropoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate (Example 9a) in 30 ml of tetrahydrofuran. 470 mg of 4′-(3-propylaminopropoxy)-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.=226° C., yield=64%).
