실험 절차

Finally, to a solution of 1-benzyloxy-18-(p-iodophenyl)octadecane (Compound V) (185 mg; 0.33 mmol) and anisole (0.15 ml; 1.32 mmol) in dichloromethane (3 ml) was added anhydrous aluminum chloride (135 mg; 1 mmol) at the room temperature. Stirring was continued for 2 h. The reaction was quenched by diluted hydrochloric acid and extracted by chloroform. Extract was dried (Na2SO4) and evaporated. The residue was chromatographed in hexane-ethyl acetate (gradient from 95:5 to 85:15) to give 18-(p-iodophenyl) octadecanol, Compound VI (123 mg; 77%).
