实验步骤: To a solution of 4′-(2-iodoethyl)octanophenone (200 g) in trifluoroacetic acid (319 ml) is added triethylsilane (195.7 ml) under ice-cooling, and the mixture is stirred at room temperature for 2 hr. The reaction mixture is concentrated, and the residue is distilled away under reduced pressure to give the title compound (7) as a pale-red oil. The resulting Compound (7) has the same physico-chemical characteristics as indicated in Example 15. cooling The reaction mixture is concentrated the residue is distilled away under reduced pressure

实验步骤: To a solution of diethyl acetamidomalonate (277 g) and sodium ethylate (86.6 g) in anhydrous ethanol (850 ml) is added a solution of 2-(4-octylphenyl)ethyl iodide (7) (146 g) in anhydrous tetrahydrofuran (533 ml), and the mixture is refluxed under heating for 6 hr. The reaction mixture is concentrated and partitioned between water and hexane, and the hexane layer is washed three times with water. The obtained hexane layer is dried over anhydrous magnesium sulfate and concentrated. The residue is recrystallized from hexane to give the title compound (8) as colorless crystals. The resulting Compound (8) has the same physico-chemical characteristics as indicated in Example 7. the mixture is refluxed under heating for 6 hr The reaction mixture is concentrated partitioned between water and hexane the hexane layer is washed three times with water The obtained hexane layer is dried over anhydrous magnesium sulfate concentrated The residue is recrystallized from hexane
