Sodium hydride → N-(3,5-dimethylpyridin-2-yl)-N-isobutyl-4-((tetrahydro-2H-pyran-4-yl)methoxy)benzenesulfonamide

温度

20 °C

To a solution of N-(3,5-dimethylpyridin-2-yl)-4-fluoro-N-isobutylbenzenesulfonamide (53.7 mg, 0.160 mmol) and (tetrahydro-2H-pyran-4-yl)methanol (18.54 mg, 0.160 mmol) in dimethyl sulfoxide (DMSO) (1 mL) stirred at room temperature, was added sodium hydride (4.79 mg, 0.160 mmol, 60% wt in mineral oil). The reaction mixture was stirred at 20° C. for 2 hour, then left to stand overnight. Additional sodium hydride (4.79 mg, 0.160 mmol, 60% wt in mineral oil) was added and the reaction stirred for a further 2 hours. The reaction was quenched with methanol (0.5 mL) and water (0.5 mL), then concentrated in vacuo. The crude was purified by mass directed autoprep (formic acid modifier) to give the title compound (31.3 mg). LCMS (2 min, formic) Rt 1.38 min, m/z (ES+) 433 (M+H).
