The reaction was carried out in a 200-ml round-bottom flask fitted with reflux condenser protected by a calcium chloride tube. In order to trap the gases liberated during the reaction, the end of the calcium chloride tube was connected to a Tishchenko vessel containing a solution of caustic alkali. A solution of 20.2 g (0.1 mole) of 5-benzyl-2-furoic acid (see p. 7), m.p. 104–105°, in 50 ml of dry benzene was introduced into the flask, and a solution of 14.5 g (0.12 mole) of freshly distilled thionyl chloride in 30 ml of benzene was added.
