To a mixture of salicylaldehyde (40 mL, 45.84 g, 375.37 mmol)) and aniline (22 mL, 31.72 g, 374.66 mmol), was added ethanol (90 mL), 8 drops of concentrated hydrochloric acid and water (10 mL). This reaction mixture was refluxed for one hour, allowed to cool to room temperature and left in the refrigerator over the weekend. A large quantity of orange solid was formed after 2 hours in the refrigerator. It was filtered off and washed with ethanol. Recrystallisation from ethanol afforded 31.53 g of product.
