TMK 688 is derived trom the condensation ot 5-(3'-methoxy-4'-hydroxyphenyl)-2,4-pentadienoic acid (IV) and N-aminoethyl 4-diphenylmethoxypiperidine (X) in the presence of ethyl chloroformate in dichloromethane. Synthesis of intermediate (IV): Vanillin (I) is protected with ethyl chloroformate to give (II), which is then treated with triethyl 4-phosphonocrotonate and followed by alkali hydrolysis to produce (IV).
