Procedure

In a manner similar to that of Example 2b, by reacting 730 mg of ethyl 4′-[3-(tert-butyldimethylsilanyloxy)propoxy]-4″-diethylamino[1,1′;3′,1″]terphenyl-4-carboxylate (1.3 mmol) in 25 mL of tetrahydrofuran with 1.6 mL of 1M tetrabutylammonium fluoride. 430 mg of ethyl 4″-diethylamino-4′-(3-hydroxypropoxy)-[1,1′;3′,1″]terphenyl-4-carboxylate are obtained (yield=74%).
