| Product | N-(2-Amino-2-methylpropyl)-N'-methylurea | HCID 54538017 | 90% |
Reaction Steps
A reaction mixture of 5.7 g (1 mol) of methyl isocyanate and 20 ml of pyridine was stirred at 0° C. for 5 minutes and slowly added into a solution of 20 g (0.23 mol) 1,2-diamino-2-methylpropane in 30 ml of pyridine. The reaction mixture was warmed to 20° C. and stirred for 1 hour. Evaporation of the solvent in vacuo gave 11.6 g (90%) of product which was identified by NMR and IR spectroscopy.
