実験手順

To a mixture of 4-bromo-N-[5-(cis-3,5-dimethyl-1-piperazinyl)-2-(methyloxy)phenyl]-3-fluorobenzenesulfonamide (E105) (100 mg, 0.21 mmol) and 3-furanylboronic acid (47 mg, 0.42 mmol) in DME (3 ml) was added potassium tert-butoxide (212 mg, 1.89 mmol) and tetrakis(triphenylphosphine)palladium(0) (12 mg, 0.01 mmol) in water (1 ml) and the resulting mixture stirred in a microwave (set at high absorbance) at 100° C. for 30 minutes. The solvent was evaporated with the addition of a few drops of toluene and the residue passed through an SCX column eluting with methanol followed by 2M ammonia in methanol. The basic fractions were combined and the solvent evaporated. The crude product was purified by mass directed autoprep HPLC and the relevant fractions collected and solvent evaporated to afford the title compound (E116). MS (ES+) m/e 460 [M+H]+.
