The mixture was subsequently stirred at reflux for 4 hours. After cooling, it was extracted by stirring with water, the organic phase was dried and concentrated, to give a colorless oil which crystallized after trituration with petroleum ether. Filtration with suction left 70.5 g (67.0% of theory) of colorless crystals.
