4-(Diethylamino)phenylboronic acid → Ethyl 4'-[3-(tert-butyldimethylsilanyloxy)propoxy]-4''-diethylamino[1,1';3',1'']terphenyl-4-carboxylate

Participants

Reaction Steps

In a manner similar to that of Example 1d, by reacting 1 g of ethyl 3′-bromo-4′-[3-(tert-butyldimethylsilanyloxy)propoxy]biphenyl-4-carboxylate (2 mmol) with 580 mg of 4-diethylaminophenylboronic acid (3 mmol) in the presence of tetrakis(triphenylphosphine)palladium. 1.15 g of ethyl 4′-[3-(tert-butyldimethylsilanyloxy)propoxy]-4″-diethylamino[1,1′;3′,1″]terphenyl-4-carboxylate (yield=100%) are obtained in the form of a colorless oil.
