Procedure
A solution of 0.01 moles of benzyl 2'-cyano-4-biphenylylglycolate dissolved in 100 ml. of acetic acid and containing 0.01 mole of hydrogen chloride is shaken with hydrogen over a 5% Pd carbon catalyst until 0.01 moles of hydrogen is absorbed. The catalyst is then filtered and the solution is evaporated to dryness and crystallized to obtain 2'-cyano-4-biphenylylglycolic acid.
