실험 절차

8.9 g (0.10 mole) of ethyl carbamate was dissolved in 18.6 g (0.10 mole) of 2-ethylhexyl glycidyl ether. After adding 0.41 g of N, N-dimethylbenzylamine and 0 63 g of di-n-butyltin dilaurate, the solution was heated at 160° C. for 1 hour while blowing nitrogen gas into the reaction mixture. The product was distilled under reduced pressure to give 20.0 g (88% of theory) of 5-(2-ethylhexyl) oxymethyl-2-oxazolidinone.
