Procedure

To a mixture of ethyl 4-[3-(4-hydroxybenzoyl)indol-1-yl]butyrate (275 mg), (R)-1-(4-isobutylphenyl)pentan-1-ol (179 mg) and triphenylphosphine (213 mg) in a mixture of tetrahydrofuran and toluene (1:4, 10 ml) was added diethyl azodicarboxylate (0.13 ml) at -25° C. After stirring for 1 hour, the reaction mixture was concentrated in vacuo. The concentrate was chromatographed on silica gel using hexane and ethyl acetate (3:1) to give ethyl (S)-4-[3-[4-[1-(4-isobutylphenyl)pentyloxy]benzoyl]indol-1-yl]butyrate (279 mg).
