반응 단계

In a nitrogen atmosphere, 24.8 g. (0.3 mole) 2-methyl-2-aminopropionitrile and 30.7 g. (0.3 mole) t-butyl isocyanate, 97%, are combined and stirred for 5 minutes. At the end of this period, the mixture is filtered and 1 ml. of pyridine is added to the filtrate. This mixture is heated in an oil bath for one and one-half hours, keeping the temperature of the bath below 70°. The solid is recrystallized from methanol:water, 60:40, to give N-(1-cyano-1-methylethyl)-N'-(1,1-dimethylethyl)urea, m.p. 204°-5°; Anal. Calcd. for C9H17N3O; C: 58.99, H: 9.35, N: 22.93; Found: C: 59.21, H: 9.26, N: 22.59.
