Ethylene Glycol → HCID 86738507, compound

Participants

Reaction Steps

A mixture of 2.0 g (6.5 mmole) of 27d, 1.25 (20.0 mmole) of ethyleneglycol, and 1.0 g of p-toluenesulfonic acid monohydrate is refluxed in 50 ml of benzene in a Dean-Stark apparatus until the collection of water ceases. The reaction mixture is cooled, washed with saturated NaHCO3 solution and brine, dried over MgSO4, and filtered. The filtrate is stirred with 2.2 g (10 mmole) of di-t-butyldicarbonate at reflux temperature and then concentrated to a solid residue and recrystallized from benzene/hexane to yield the title compound.
