The obtained mixture was then decomposed by the addition of 100 ml of a saturated aqueous solution of Na2CO3, extracted with ether (3×50 ml), washed with water (3×50 ml) and dried over Na2SO4. After evaporation there were obtained 8 g of crude material which by distillation at 0.02 Torr gave the desired compound in a 58% yield.
