Reaction Steps
To a suspension of 4-Methoxycarbonylphenyl boronic acid (648 mg) and 4-iodo-1-heptylpyrazole (876 mg) and Pd(PPh3)4 (173 mg) in 1,2-dimethoxyethane (10 ml) was added 2M Na2CO3 aq. (3.6 ml). The reaction mixture was stirred at 80° C. for 2 hours under N2 atmosphere, and poured into ice-water and extracted with ethyl acetate. The organic layer was washed with brine, and dried over MgSO4. The solvent was removed under pressure. The residue was subjected to column-chromatography on silica gel 60 (Merk) and eluted with n-hexane/ethyl acetate (80:20). The fractions containing the object compound were combined and evaporated under reduced pressure to give 1-heptyl-4-(4-methoxycarbonylphenyl)pyrazole (0.20 g).
