A process for the preparation of optically active cyclohexylglycolate esters is described. The process utilizes carboxylic acid activation to couple (R)- or (S)-cyclohexylphenylglycolic acid (CHPGA) with 4-N,N-diethylamino butynol or other propargyl alcohol derivatives. The preparation of the hydrochloride salt is also described.
