Versuchsvorschrift
A mixture of ethyl 2-cyano-2-[2-methoxy-3-(o-tolyloxy)phenyl]propionate (6.1 g), conc. hydrochloric acid (20 ml) and acetic acid (40 ml) was refluxed under heating for 48 hours. The reaction mixture was treated in a similar manner to that of Example 10-(6) to give oily 2-[2-methoxy-3-(o-tolyloxy)phenyl]propionic acid (2.9 g).
