실험 절차

Into a 100 ml reaction flask equipped with reflux condenser, thermometer, hot plate, spin bar and heating mantle are placed 12.8 grams of cyclooctanol; 22 grams of 2-mercaptopropionic acid and 0.5 grams of paratoluene sulfonic acid. The reaction mass is heated to reflux and maintained at reflux for a period of 10 hours. At the end of the reaction mass, the reaction product is washed with one 25 ml volume of water and dried over anhydrous sodium sulfate. The reaction mass is then distilled on a micro distillation column yielding the compound having the structure: ##STR99##
