Reaction Steps

To a mixture of 4-bromo-2-chloro-N-[5-(cis-3,5-dimethyl-1-piperazinyl)-2-(methyloxy)phenyl]benzenesulfonamide (E104) (150 mg, 0.31 mmol) and 2-furanylboronic acid (69 mg, 0.62 mmol) in DME (3 ml) was added potassium tert-butoxide (312 mg, 2.8 mmol) and tetrakis(triphenylphosphine)palladium(0) (20 mg, 0.017 mmol) in water (1 ml) and the resulting mixture stirred in a microwave (set at high absorbance) at 100° C. for 30 minutes. The resulting mixture was then purified using an SCX cartridge followed by mass directed autoprep HPLC to afford the title compound (E308). MS (ES+) m/e 476/478 [M+H]+.
