Reaction Steps
26(a) A solution of 42.57 g of ethyl 3-oxostearate (prepared as described in Preparation 25). 9.71 g of ethylene glycol and 1 g of camphorsulfonic acid in 200 ml of toluene was heated under reflux for 24 hours, and the water produced was removed through a side arm attached to a water separator. The mixture was allowed to cool, and then washed, in turn, with a saturated aqueous solution of sodium bicarbonate and with water. It was then dried and concentrated by evaporation under reduced pressure, to give 29.66 g of crude ethyl 3,3-ethylenedioxystearate.
