Benzenesulfonyl chloride → N-(3-(6-(4-methoxyphenyl)-9H-pyrido[2,3-b]indol-3-yl)phenyl)benzenesulfonamide

Participants

Reaction Steps

To a solution of 3-(6-(4-methoxyphenyl)-9H-pyrido[2,3-b]indol-3-yl)benzenamine (23 mg, 0.06 mmol, 1 equiv.), in anhydrous pyridine (0.300 ml), benzenesulfonyl chloride (0.009 ml) is added under argon. The reaction is carried out at room temperature for 3 hours and is then quenched with H2O (5 ml). The aqueous layer is extracted with AcOEt (3×5 ml) and CH2Cl2 (5 ml). The organic layers are dried over MgSO4 and concentrated under reduced pressure. The crude product is purified over silica gel chromatography (eluant CH2Cl2/AcOEt 7:3) to afford the product as a white solid (15 mg, 0.03 mmol) in 50% yield.
