113.8 g of methyl 2,4-dimethoxycinnamate are dissolved in 1.5 1 of methanol while heating and are hydrogenated on 5 g of catalyst (10% Pd/C). The catalyst is removed by filtration and the filtrate is concentrated. 113 g of an oil remain and are immediately used in the subsequent Friedel-Crafts acylation.
