| Reactant | Ammonia | HCID 222 | — |
| Reactant | 2-Oxoimidazolidine-1-carbonyl chloride | HCID 83241 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | 2-oxoimidazolidine-1-carboxamide | HCID 262110 | — |
Reaction Steps
29.7 parts by weight of N-chlorocarbonyl-imidazolid-2-one, were reacted at pH = 8.5 and room temperature with 20 parts by volume of 25% strength aqueous solution of NH3 in 80% strength aqueous tetrahydrofurane. After stripping off the tetrahydrofurane in vacuo, the product which precipitated was filtered off and washed with a little ice water. Yield after drying over P2O5 in a desiccator: 62%. Melting point 200° C.
