Procedure

(E)-Methyl 3-(2-methyl-4-phenyl-3-pyridinyl)-2-propenoate (7.10 g, 0.028 mol) was dissolved in 500 ml of ethanol under a nitrogen atmosphere. Palladium on activated charcoal (0.14 g, 10%) was added in one portion. The nitrogen atmosphere was evacuated, and hydrogen was introduced. After vigorous shaking for 40 hours, the reaction mixture was filtered under a stream of nitrogen and evaporated under reduced pressure to yield 7.18 g of methyl 2-methyl-4-phenyl-3-pyridinepropanoate.
