| Product | N-(p-phenylbenzylidene)-p-methylaniline | HCID 13017554 | — |
Reaction Steps
p-Toluidine (0.20 mole), 4-biphenylcarboxaldehyde (0.20 mole), and IRC-50 (weakly acidic) ion exchange resin (0.5 g.) were azeotropically refluxed in toluene (150 cc). The required amount of water had been removed after 3 hours. The solvent was removed on the rotary evaporator and the residue was recrystallized with 95% ethanol to yield N-(p-phenylbenzylidene)-p-methylaniline; m.p. 137°-139° C.
