Reaktionsschritte

To a stirred solution of methyl 4-(cis-2-phenyl- 1-cyclohexanoyloxy)-2-methoxybenzoate (230 mg, 0.64 mmol) in THF:H2O (5 mL:1 mL) was added LiOH.H2O (113.5 mg, 2.7 mmol). The reaction was heated to 45° C. over 12 h and then cooled to ambient temperature. The solvent was removed under reduced pressure. The crude solid was passed through a small plug of silca gel packed in 90:10 CH2Cl2 :MeOH(NH3) and eluted with same. The solvent was removed under reduced pressure to afford 4-(cis-2-phenyl-1-cyclohexanoyloxy)-2-methoxy-benzoic acid as a foam.
