실험 절차

To a solution of N-(4-chloro-2-fluoro-5-hydroxyphenyl)-3,4,5,6-tetrahydrophthalimide (3 g) in dimethylformamide (100 ml), anhydrous potassium carbonate (0.8 g) and then amyl chloroacetate (1.9 g) were added, and the resultant mixture was heated at 70° to 80° C. for 3 hours. The reaction mixture was cooled to room temperature, admixed with water and extracted with diethyl ether. The etheral layer was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the compound (I) (1.8 g).
