Reaction Steps

Morpholine (0.27 ml, 3.3 mmol) and tetrakis(triphenylphosphine)palladium (0) (57 mg, 0.049 mmol) were successively added to a solution of tert-butyl 2-(allyloxy)-6-{[(4′-{[(allyloxy)carbonyl]methyl}-3′-fluoro-1,1′-biphenyl-4-yl)oxy]methyl}-3-(trifluoromethyl)benzoate (790 mg, 1.32 mmol) obtained in Example (11-6) in tetrahydrofuran (8 ml), and the mixture was stirred at room temperature for 1 hour. After water was poured into the reaction mixture and the mixture was extracted with ethyl acetate, the organic layer was successively washed with water and a saturated aqueous NaCl solution and dried with anhydrous sodium sulfate. After the residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (eluting solvent: n-hexane/ethyl acetate=3/1-0/1), it was crystallized from a mixture solvent of methylene chloride-ethyl acetate to give the title compound as a colorless powder (323 mg, yield: 47%).
