반응 단계
A mixture of 100 grams (1.0 mole) of hydantoin, 151 grams (1.0 mole) of 4-nitrobenzaldehyde, 77 grams (1.0 mole) of ammonium acetate, 120 grams (2.0 moles) of acetic acid, and 200 ml of n-butanol were held for 3 hours at reflux temperature. After the cooling, there were obtained 219 grams of 5-(4'-nitrobenzylidene)-hydantoin, corresponding to 94% of the theory based on hydantoin. The product had a melting point of 253°-254° C. and homogeneous by thin layer chromatography.
