Methanol was distilled off from the mixture under ordinal pressure, and the mixture was stirred at 100° C. for an hour. The reaction mixture was cooled, acidified with conc. hydrochloric acid and extracted with diethyl ether. The extract was washed with water, dried and evaporated under reduced pressure to give oily 2-(o-tolylthio)-6-(1-propenyl)phenol (24.3 g).
