Versuchsvorschrift

The obtained 4-methoxy-4′-(di-p-tolylamino)stilbene and two equivalent amounts of sodium ethanethiolate were dissolved into N,N-dimethylformamide, allowing reaction to proceed at 130° C. for 5 hours. The solution was cooled, added in water, and neutralized with hydrochloric acid, and the target product was extracted with ethyl acetate. The extract liquid was washed with water and dried, and solvent was removed to obtain a crude product, which was then purified by column chromatography on silica gel to give 4-hydroxy-4′-(di-p-tolylamino)stilbene (CTP-1), a target product.
