HCID 57971179, compound → 6-(3,3-Diethoxypropyl)quinoline

Participants

Reaction Steps

A mixture of 6-(3,3-diethoxyprop-1-yn-1-yl)quinoline (22, 56 mg, 0.22 mmol) and 10% palladium on carbon (5 mg) in THF (5 mL) was hydrogenated under H2 at 1 atm for 6 h. The reaction mixture was filtered through a celite bed and the celite bed was washed with THF (2×2 mL). The combined filtrates were concentrated under the reduced pressure to afford 6-(3,3-diethoxypropyl)quinoline (23, 56 mg, 57 mg theoretical, 98% yield) as a clear oil, which was found to be sufficiently pure to be used in the subsequent reaction without further purification and was identical to the material made from Method A in every comparable aspect.
