To a solution of 2-chloro-N-(3,5-dimethylpyridin-2-yl)-4-fluorobenzenesulfonamide (117 mg, 0.372 mmol) in acetonitrile (4 mL) stirred at room temperature, was added N″-(1,1-dimethylethyl)-N,N,N′,N′-tetramethylguanidine (127 mg, 0.743 mmol). The reaction mixture was stirred at room temperature for 1 hour, then 1-bromo-2-methylpropane (0.081 mL, 0.743 mmol) was added. The reaction vessel was sealed and heated under microwaves at 150° C. for 30 minutes. The solvent was evaporated in vacuo and the crude was purified by mass directed autoprep (ammonium carbonate modifier) to give the title compound (8.4 mg). LCMS (2 min, High pH) Rt 1.45 min, m/z (ES+) 371 (M+H).
