Procedure

0.64 Grams (0.005 moles) of 2,5-dimethyl-3-furanthiol and 1.04 grams (0.01 moles) of isoamyl mercaptan are dissolved in 12 ml anhydrous diethyl ether. 0.8 Grams (0.0075 moles) of sodium carbonate dissolved in 8 ml water is added with stirring to the reaction mass. 1.9 Grams (0.0075 moles) of iodine dissolved in 6 ml anhydrous diethyl ether is then added dropwise to the reaction mass until the iodine color remains. The reaction mass is then stirred for a period of 30 minutes.
