Methanol → 1-Methyl-3-n-propyl-2-iminoimidazolidin-4-one

Participants

Reaction Steps

2.83 g (10 mmol) of the 1-methyl-3-n-propyl-2-iminoimidazolidin-4-one hydroiodide was added to 25 ml of methanol containing 0.66 g (10 mmol) of 85% potassium hydroxide, and the mixture was stirred at room temperature for one hour. Methanol was distilled off under reduced pressure, and chloroform was added to the residue. Precipitated crystals were removed by filtration. Chloroform was distilled off under reduced pressure to obtain 1.16 g of 1-methyl-3-n-propyl-2-iminoimidazolidin-4-one as an oily substance.
