Procedure

Ethyl p-methoxy-α-methylcinnamate (39.1 g) is dissolved in 186 ml of 2B ethanol. This solution is shaken with 1.5 g of 10% palladium on carbon at an initial pressure of 60 psi until the uptake of hydrogen is 100%. The reaction mixture is removed on an evaporator leaving ethyl β-(p-methoxyphenyl)-α-methylpropionate.
