A DMF (2 mL) solution of [3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]propiolic acid (74 mg) and 9-aminofluorene (65 mg) and BOP (133 mg) and N,N′-IPEA (77 μL) was agitated at room temperature overnight. Water and chloroform were added to the reaction solution, the organic layer was partitioned and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Carrier: Chromatorex NH, elution solvent:heptane-ethyl acetate system), and 45 mg of the title compound was obtained.
