Participants

Reaction Steps

3.0 g of methyl N-propargyl-N-methoxycarbonylglycinate were dissolved in 40 ml of 28% aqueous ammonia. Then the mixture was maintained under the pressure of 10-13 kg/cm2 at 100°-110° C. for an hour. Then the solvent was evaporated off from the reaction mixture. The resulting mixture was subjected to a column chromatography on silica gel (5:1 ethyl acetate:methanol as eluent) to obtain 0.65 g of 1-propargyl-2,4-dioxoimidazolidine.
