2-Pyrrolidinone, 1,1'-(3-methyl-1-propene-1,3-diyl)bis- → 41033-13-0

Participants

Reaction Steps

60 g of 1,3-bis-(1-pyrrolidonyl)butene, 1000 ml of glacial acetic acid and 10 g of 10% palladium on carbon were mixed under inert gas. Subsequently, hydrogen was passed in while stirring at room temperature. The hydrogen uptake was complete after about 30 min. Reaction was allowed to continue at room temperature for a further 90 min. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The oily crude product was subsequently distilled under reduced pressure.
