In 250 mL of water, was subsequently added and dissolved 68.7 g (321 mmol) of sodium periodate. A methanol solution (250 mL) of 49.6 g (306 mmol) of 4-methyl-1-prop-2-ynylthiobenzene [general formula (XI)] was dropped and stirred at room temperature for 2.5 hours. After 2.5 hours, the mixture was filtered, and the solids were washed with 100 mL of ethyl acetate. The filtrate was vacuum concentrated, and 200 mL of water was added. The resulting mixture was extracted with ethyl acetate (150 mL) three times. The obtained organic layers were washed with 150 mL of water, dried with magnesium sulfate and vacuum concentrated to provide 50.6 g (crude yield 93%) of 4-methyl-1-(prop-2-ynylsulfinyl)benzene.
