Sodium Hydroxide → 4'-(3-Aminopropoxy)-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 140 mg (3.5 mmol) of sodium hydroxide with 170 mg (0.35 mmol) of ethyl 4′-(3-aminopropoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate (Example 17b) in 30 ml of tetrahydrofuran. 95 mg of 4′-(3-aminopropoxy)-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.=243° C., yield=49%).
