Participants

Reaction Steps

0.5 g (1.4 mmol) of 4'-(2-heptylpyridin-5-yl)-4-cyanobiphenyl and 0.5 g of sodium hydroxide were added to 20 ml of diethylene glycol and refluxed for 12 hours. By adding 200 ml of a 3% aqueous hydrochloric acid solution to the reaction solution, crystals were precipitated, separated by filtration and dried with air. The solid was recrystallized from acetic acid, to obtain 0.5 g of 4'-(2-heptylpyridin-5-yl)-4-biphenyl carboxylic acid. The melting thereof was above 250° C.
