Reaktionsschritte

Phenol (3.0 g.) was converted into its sodium salt by dissolving in a freshly prepared sodium methoxide-methanol solution (0.7 g. of metallic sodium in 50 ml. of absolute methanol), and subsequent evaporation of the excess methanol under reduced pressure on a rotary evaporator. The solid residue was dissolved in acetonitrile (250 ml.) by stirring with 18-crown-6 (0.9 g.) for 30 minutes at room temperature. N-(1-methylethyl)-3-phenyl-2-oxiranecarboxamide (6.16 g.) was added to the solution, and the resulting mixture was heated under reflux for 6 hours. After cooling to room temperature, it was filtered. The filtrate was evaporated on a rotary evaporator under reduced pressure to give a resinous material. Water (ca. 200 ml.) was added to the residue, and allowed to stand at room temperature. The white precipitate thus separated was collected on a filter and washed with water. The filter residue was dried in air, then recrystallized from ethanol, giving 2.5 g. of product, m.p. 166°-168°.
