Pyridine → HCID 54073489, compound

Participants

Reaction Steps

A mixture of 20.0 g. of 3-hydroxy-3-methyl-undec-1-yne, 200 ml. of pyridine, and 500 mg. of 5% palladium on barium sulfate is shaken in hydrogen at an initial pressure of 45 lb./sq. in. The hydrogenation is stopped when the calculated amount for one mole uptake per mole of compound has been absorbed. The mixture is poured into water and extracted with ether. The ether extract is washed with water, dilute hydrochloric acid, aqueous sodium bicarbonate, dried, and evaporated under reduced pressure to give a residue which is distilled through a Vigreaux column to give a distillate comprising 3-hydroxy-3-methyl-1,5-undecadiene.
