4,4-Diaminodiphenylmethane → HCID 2803143, compound

Participants

Reaction Steps

To a solution of 198.2 g (1 mole) of 4,4'-methylene dianiline in 2000 ml of ethanol was added a solution of 277.6 g (2.1 moles) of transcinnamaldehyde in 500 ml of ethanol over a 2 minute period. Immediately an exothermic reaction ensued and within 2 minutes the reaction mixture set up to a yellow solid. An additional 1000 ml of ethanol was added, the reaction mixture was heated at reflux for 1 hour with stirring, and then cooled to room temperature. The product was filtered and dried in vacuum at room temperature, yielding 402.5 g (94% of theory) of N,N'-biscinnamal-4,4'-methylene dianiline, m.p. 162.5°-163.5°C.
