実験手順

Into a 25 mm micro flask equipped with spin bar, hot plate (having built in magnetic stirrer), reflux condenser and thermometer are placed 5 grams (0.0284 moles) of methyl-4-(propylthio)butyrate; 8.4 grams (0.1136 moles) of isobutanol and 0.05 grams of para-toluene sulfonic acid. The reaction mass is heated to reflux and maintained at reflux with stirring for a period of 14.5 hours. At the end of the refluxing, the reaction mass is cooled and distilled on a micro Vigreux column yielding the following fractions:
