Triethylamine → HCID 10997279, compound

Participants

Reaction Steps

In 500 ml of carbon tetrachloride, 50.5 g of the (2S,5S)-5-bromo-2-tert-butyl-5-methyl-1,3-dioxolan-4-one obtained in Step 2 was dissolved. To the resulting solution, 50.0 g of triethylamine was added, and the solution was refluxed for 4 hours. After the reaction solution was left to have cooled, insolubles were separated by filtration, the carbon tetrachloride was evaporated under reduced pressure, and the resulting residue was recrystallized from hexane to obtain 29.5 g of (2S)-2-tert-butyl-5-methylene-1,3-dioxolan-4-one.
