Procedimiento

p-Toluidine (0.20 mole), acetophenone (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, and the residue was distilled under reduced pressure to give N-(α-methylbenzylidene)-p-toluidine. b.p. 129°-37° C./0.05 mm.
