Procedure
After allyl alcohol (7.0 ml, 103 mmol) and concentrated sulfuric acid (0.1 ml) were successively added to a solution of (2′-chloro-4′-hydroxy-1,1′-biphenyl-4-yl)acetic acid (1.93 g, 7.35 mmol) obtained in Example (13-1) in benzene (30 ml), the mixture was heated under reflux for 1 hour. The reaction mixture was poured into water and extracted with ethyl acetate (twice). 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=90/10-65/35) to give allyl (2′-chloro-4′-hydroxy-1,1′-biphenyl-4-yl)acetate as a white powder (1.97 g, yield: 899.
