실험 절차
Equivalent quantities of 2-perimidinemethanol and sodium hydride are heated for 1/2 hour in dimethoxyethane. After the evolution of hydrogen has stopped, ethyl chloroformate is added to the solution, and the resulting mixture is stirred for 3 hours, poured into water and the separated solid collected and recrystallized twice from dimethoxyethane to give the desired product, 1H, 3H-oxazolo[3,4-a]perimidine-3-one, m.p. 194°-195°.
