Methyl Isocyanate → HCID 13228828, compound

Participants

Reaction Steps

N-((((1,1-dimethylethyl)amino)carbonyl)oxy)acetamide (8.7 grams), methyl isocyanate (3.2 grams), and a few drops of triethylamine were stirred at room temperature in 150 ml of methylene chloride for about 12 hours. The solvent was then removed under vacuum leaving an oily residue which was dissolved in hot toluene. Upon cooling, a white crystalline material separated and was collected by filtration. The white crystals were recrystallized from toluene leaving a residue which was mixed with about 50 ml of water for two hours. This mixture was then filtered, and the insoluble material was dried in a vacuum leaving the desired N-((methylamino)carbonyl)-N-((((1,1-dimethylethyl)amino)carbonyl)oxy)acetamide, m.p. 142°-144° C.
