Equal molar amounts of diethyl 4-methoxybenzylphosphonate and 4-(di-p-tolylamino)benzaldehyde were dissolved into N,N-dimethylformamide, and with agitation under water cooling, t-butoxy potassium was added little by little. After agitation for 5 hours at room temperature, water was added, and the solution was rendered acidic so that crude target product precipitates. The crude target product was purified by column chromatography on silica gel to give 4-methoxy-4′-(di-p-tolylamino)stilbene.
