Methyl Isocyanate → HCID 54023924, compound

Participants

Reaction Steps

A mixture of 10 g (0.045 m) of 1-(carbamoylmethylthio)-2-nitro-2-methylpropionaldoxime, 150 ml. acetonitrile, 8.0 g (0.14 m) of methylisocyanate and three drops of triethylamine was allowed to stand at room temperature, with occasional shaking, for twenty hours. The acetonitrile and excess methyl isocyanate was removed from the product under reduced pressure. The solid residue was recrystallized from isopropanol and then dried at room temperature to give 9.0 g (72% yield) of 1-(carbamoylmethylthio)-2-nitro-2-methylpropionaldehyde O-(methylcarbamoyl)oxime; melting point=125-127° C. The nmr spectra confirmed the structure.
