الإجراء التجريبي

An equimolar mixture of 27.4 g (0.18 mol) 4-hydroxy-2-methoxybenzaldehyde and 28.3 g (0.18 mol) benzenesulfonamide was placed into toluene. 100 mg p-toluenesulfonic acid was added as a catalyst. The mixture was then heated under reflux on a water separator until the theoretically calculated quantity of water had separated. After cooling to room temperature, the precipitated solid was filtered off and dried under vacuum. Yield: 43.0 g (78.9%).
