Методика

To a mixture of 100 grams (1.0 mole) of hydantoin, 106 grams (1.0 mole) of benzaldehyde, and 370 grams (5.0 moles) of propionic acid, there were added 17 grams (1.0 mole) of ammonia. The mixture was subsequently held for 3 hours at reflux temperature. After the cooling off, there were obtained 178 grams of 5-benzylidene hydantoin, corresponding to 95% of theory based on hydantoin.
