Reaction Conditions

Reaction Steps

2 ml (2.0 mmol) of an aqueous solution of sodium hydroxide (1M) are added to a solution of 0.20 g (0.40 mmol) of ethyl 4′-(4-hydroxybutoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)biphenyl-4-carboxylate in 8 ml of tetrahydrofuran. The reaction mixture is stirred for 48 h while heating at 40° C. The reaction mixture is placed under a stream of nitrogen in order to eliminate the tetrahydrofuran and then 2.4 ml (2.4 mmol) of a solution of hydrochloric acid (1M) are added. The product precipitates in the form of a white solid. After filtration, the product is washed twice with 5 ml of diethyl ether and then dried in an oven under vacuum overnight. 0.17 g of 4′-(4-hydroxybutoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)biphenyl-4-carboxylic acid is obtained (white solid, Mp 235° C., yield=90%).
