Procedure

tert-Butyl 2-(allyloxy)-6-{[(4′-{[(allyloxy)carbonyl]methyl}-3′-fluoro-1,1′-biphenyl-4-yl)oxy]methyl}-3-(trifluoromethyl)benzoate (200 mg, 0.33 mmol) obtained in Example (11-6) was dissolved in toluene (3 ml) and N,N-dimethylformamide di-tert-butyl acetal (0.4 ml, 1.7 mmol) was added thereto, and the mixture was heated under reflux for 3 hours. After the reaction mixture was poured into water and the mixture was extracted with ethyl acetate (three times), the organic layer was successively washed with water (twice) and a saturated aqueous NaCl solution and dried with anhydrous sodium sulfate. The residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (eluting solvent: n-hexane/ethyl acetate=10/1-1/1) to give tert-butyl 2-(allyloxy)-6-{[(4′-{1-[(allyloxy)carbonyl]-2-(dimethylamino)vinyl}-3′-fluoro-1,1′-biphenyl-4-yl)oxy]methyl}-3-(trifluoromethyl)benzoate (141 mg, yield: 65%).
