Ethyl 5-(prop-1-en-2-yl)pyridine-2-carboxylate → Ethyl 5-(propan-2-yl)pyridine-2-carboxylate

Participants

Reaction Steps

10% palladium-activated carbon (5.8 g) was added to a solution of ethyl 5-(prop-1-en-2-yl)pyridine-2-carboxylate (10 g) in ethanol (100 mL), and the mixture was stirred in a hydrogen gas stream at room temperature overnight. The reaction solution was filtered through celite, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=9:1→0:1) to give ethyl 5-isopropylpyridine-2-carboxylate as a colorless oil (10 g, 95%).
