15 g of palladium on carbon (10% and 30 ml of water are added to a mixture of 155 g of 4-nitrocinnamic acid in 1 l of methanol, and hydrogenation is carried out at room temperature under 3 bar until no further hydrogen is taken up, after about 2 hours. After filtration and evaporation of the solvent in a rotary evaporator, residual water is removed by twice adding 300 ml portions of toluene and distilling off the solvent in a rotary evaporator.
