実験手順

To the mixture of 3-fluorobenzeneboronic acid (25.0 mg, 0.180 mmol) and 5-Bromo-3-[isopropyl-(4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (24 mg, 0.060 mmol) in 5:1 mixture of toluene/MeOH (1.0 mL) was added a solution of Pd(PPh3)4 (7.0 mg, 0.006 mmol, 10 mol %) in toluene (0.5 mL) followed by aqueous 2M Na2CO3 solution (0.06 mL, 0.120 mmol). The resultant reaction mixture was heated at 70° C. for 18 h, cooled to room temperature, filtered off through MgSO4 and washed with EtOAc. Evaporation of the solvent and purification of the residue over preparative TLC using ethyl acetate/hexane (20:80) as an eluent furnished (25.0 mg, 99% yield) of 5-(3-Fluoro-phenyl)-3-[isopropyl-(4-methyl-cyclohexanecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester.
