Same mol of the diethyl 4-methoxybenzylphosphonate and 4-(di-para-tolylamino)benzaldehyde were dissolved in N.N-dimethylformamide, and tert-butoxy kalium was gradually added to the solution while water-cooled and stirred. After stirred for 5 hrs at a room temperature, water was added thereto to acidize the solution and a crude product is separated out. The crude product was further column-refined with silica gel to prepare 4-methoxy-4′-(di-para-tolylamino)stilbene.
