Reaktionsschritte

To a stirred solution of 4-((3,5-dimethylisoxazol-4-yl)methoxy)-N-(5-isopropylpyridin-2-yl)benzenesulfonamide (150 mg, 0.37 mmol) in acetonitrile (4 mL) was added 2-(tert-butyl)-1,1,3,3-tetramethylguanidine (128 mg, 0.75 mmol). The reaction mixture was stirred at 20° C. for 1 hour. 1-Bromo-3-methylbutane (0.09 mL, 0.75 mmol) was then added and the reaction vessel sealed and heated by microwaves to 150° C. for 30 minutes. The reaction mixture was concentrated in vacuo and diluted with ethyl acetate. The organic phase was washed with water, dried using a hydrophobic frit and evaporated in vacuo to give the crude product. The crude was then purified by flash silica (Si) chromatography (0-25% ethyl acetate-cyclohexane gradient). The appropriate fractions were combined and evaporated in vacuo to give the title compound (48 mg) as a yellow oil. LCMS (2 min, HpH) Rt 1.50 min, m/z (ES+) 472 (M+H).
