Urea → Urea neopentane

4 g urea were dissolved in 12 ml ethanol at 60° C. The solution was then placed in a high pressure autoclave and subjected to a neopentane pressure of 150 bar. The solution was cooled down from 60° C. to room temperature within 48 h. The solution with h/g crystals was removed from the autoclave, filtered and the h/g crystals were washed with 10 ml cold ethanol. The h/g complex crystals were dried in the vacuum cabinet at 60° C.
