Quinoline → 2,4,5-Trifluorobenzoic acid

Participants

Reaction Steps

A mixture of 2.20 g (0.01 mole) of 2,4,5-trifluoroisophthalic acid (dried under high vacuum). 1.0 ml of quinoline and 0.23 g of copper powder was heated on an oil bath at 200° C. After a while, the mixture liquefied and released a gas (ca. 280 ml by top purging). After the gas had been completely released, the liquefied mixture was cooled to room temperature, followed by addition of 15 ml of a mixture (1:1 by weight) of conc. HCl and water.
