Versuchsvorschrift
Polyphosphoric acid (1 kg) was stirred and heated to 95°-100° C. and 4-(2-Carboxyethyl)phenylacetic acid (100 g, 0.48 mol) added over 10 minutes. The mixture was stirred for 0.5 hours and poured into ice and H2O; the product was continuously extracted with CHCl3, and recrystallised from benzene to give the title product, m.p. 133°-5° C.
