Versuchsvorschrift

In a 2 mL microwave vial, phenyl boronic acid (75 mg, 0.6 mmol), N-(2-cyano-4-bromophenyl)sulfamide (Example 83b) (137 mg, 0.5 mmol), and potassium carbonate (400 mg, 1.5 mmol) were dissolved in DME/Water mixture (1.5 mL, DME/Water 4:1). The solution was degassed by bubbling N2 gas into the reaction solution for 5 minutes and Palladium tetrakis triphenylphospine (25 mg, 0.025 mmol) was added. The reaction was placed in a microwave reactor for 5 minutes at 150° C. The crude reaction was dissolved in water and washed with ethyl acetate. The aqueous solution was evaporated under vacuum to give N-(2-Cyano-4-phenylphenyl)sulfamide.
