| titleOfInvention | Preparation of 5-(2-cyanoethyl)2,4-imidazolidinedione |
| abstract | PURPOSE: To obtain the titled compound useful as an intermediate for synthesizing organic compounds economically advantageously in high yield, by reacting 4-oxobutanenitrile with NH 3 , CO 2 , prussic acid, etc., adjusting the pH of the reaction solution with a mineral acid without evaporating it to dryness. n CONSTITUTION: One or more of 4-oxobutanenitrile, 2-hydroxypentanedinitrile and 2-aminopentanedinitrile is subjected to Bucherer-Bergs reaction with NH 3 and/or ammonium salt, CO 2 and/or carbonate, and prussic acid and/or its salt in a solvent at room temperature W150°C for 5minW10hr, the reaction solution is adjusted to ≤9pH, preferably 1W9pH with a mineral acid such as sulfuric acid, etc. without being evaporated to dryness, and crystallized at a temperature ≥the reaction temperature, to give the desired compound. n USE: Useful as an intermediate for synthesizing organic compounds such as glutamic acid, ornithine, tryptophan, etc. n COPYRIGHT: (C)1984,JPO&Japio |
