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

Participants

Reaction Steps

N-(5-chloro-3-methylpyridin-2-yl)-4-fluoro-N-isobutylbenzenesulfonamide (200.5 mg, 0.562 mmol) was dissolved in dimethyl sulfoxide DMSO (2 mL) and to this solution was added (tetrahydro-2H-pyran-4-yl)methanol (98 mg, 0.84 mmol) and sodium hydride (33 mg, 0.84 mmol, 60% wt in mineral oil). The reaction was left to stir overnight at room temperature, under nitrogen. The reaction was concentrated under a stream of nitrogen, then the crude product was extracted to the organic phase of an aqueous work up between ethyl acetate and water. The organic phase was passed through a hydrophobic frit and concentrated in vacuo to give the title compound (224 mg). LCMS (2 min, formic) Rt 1.42 min, m/z (ES+) 453 (M+H).
