5-Bromo-2-Furoic Acid,o absorb hydrogen bromide liberated in the reaction, the top of the condenser was connected to a Tishchenko vessel containing a solution of alkali. A mixture of 112 g (1 mole) of 2-furoic acid (see p. 43), m.p. 128–132°, 10 g of dry red phosphorus, and 800 ml of chloroform was prepared in the flask.
