Ethyl 3-methyl-5-phenylpent-2-enoate → Ethyl 5-phenyl-3-methylpentanoate

Participants

Reaction Steps

(1.00 g, 4.58 mmol) obtained in the above item (a) was dissolved in ethyl acetate (10 ml), and the resulting solution was subjected to hydrogen catalytic reduction by using 10% palladium-carbon (0.2 g) as a catalyst. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column chromatography (eluent: ethyl acetate/n-hexane=1/30) to obtain 0.82 g of ethyl 5-phenyl-3-methylpentanoate.
