Versuchsvorschrift

5-Benzoylfuran-2-carboxylic acid [420 mg.; Knoppova et al. Collect. Czech. Chem. Commun. 42, 3175-9 (1977), Chem. Abs. 88, 169842d] was combined with 10 ml. of hydrazine, 1.5 g. of potassium hydroxide and 10 ml. of ethylene glycol and heated for 1.5 hours in an oil bath maintained at 160° C. The mixture was cooled in an ice-water bath, diluted with water and acidified with conc. hydrochloric acid. Filtration gave 5-benzylfuran-2-carboxylic acid (250 mg., m/e 202).
