Into a 100 ml reaction flask equipped with spin bar, reflux condenser, heating mantle and hot plate with magnetic stirring apparatus is placed 5 ml cyclohexane, 0.2 grams para-toluenesulfonic acid and 3.5 grams (0.04 moles) of 2,3-butanediol. Over a period of 30 minutes, 4.1 grams (0.04 moles) of 3-methylthiopropionaldehyde is added to the reaction mass. The reaction mass is then heated to reflux and refluxed for a period of 7 hours during which water of reaction is removed.
