Reaktionsschritte

To a solution of 4-fluoro-N-(5-isopropylpyridin-2-yl)benzenesulfonamide (203 mg, 0.690 mmol) and 3-methylbutan-2-ol (60.8 mg, 0.690 mmol) in toluene (3 mL) stirred in air at room temperature was added a solution of 2-tributylphosphoranylidene)acetonitrile (166 mg, 0.690 mmol) in toluene (0.5 mL). The reaction vessel was sealed and heated by microwaves to 150° C. for 30 minutes. After cooling, the solvent was evaporated in vacuo and the crude purified by mass directed autoprep (formic acid modifier) to give the title product (32 mg) as a colourless oil. LCMS (2 min, formic) Rt 1.41 min, m/z (ES+) 365 (M+H).
