実験手順

3-(4-Carboxyphenoxy)propionic acid (2.5 g) [prepared according to the procedure of J. Lichtenberger and R. Geyer. Bull. Soc. Chim. Fr., 1963 275] in conc. sulfuric acid (20 ml) was heated to 100° C. for 4 h and then poured onto crushed ice. The resultant precipitate was filtered and dried in vacuo to give the title compound (1.6 g).
