Procedure

To a solution of cyclobutyl(2-methyl-5-phenylfuran-3-yl)methanol (364 mg) obtained by the above-mentioned reaction and methyl 4-hydroxybenzoate (274 mg) in tetrahydrofuran (20 mL) were added tributylphosphine (0.7 mL) and 1,1′-(azodicarbonyl)dipiperidine (757 mg), and the mixture was stirred at room temperature overnight. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column (0% ethyl acetate/hexane to 12% ethyl acetate/hexane) to give methyl 4-[cyclobutyl(2-methyl-5-phenylfuran-3-yl)methoxy]benzoate as an oil. The obtained methyl 4-[cyclobutyl(2-methyl-5-phenylfuran-3-yl)methoxy]benzoate was dissolved in methanol (5 mL) and tetrahydrofuran (5 mL). 2N Lithium hydroxide (1.0 mL) was added, and the mixture was stirred at 60° C. for 2 hr. The reaction mixture was poured into water, and the mixture was acidified with 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (276 mg, 47%) as an amorphous compound.
