Styrene-4-sulfonyl chloride → N-(5-isopropylpyridin-2-yl)-4-vinylbenzenesulfonamide

Participants

Reaction Steps

To a solution of 5-isopropylpyridin-2-amine (400 mg, 2.94 mmol) in pyridine (5 mL), stirred at room temperature, was added 4-vinylbenzene-1-sulfonyl chloride (760 mg, 3.75 mmol). The reaction mixture was stirred for 30 minutes then stood overnight. The solvent was evaporated in vacuo and the crude sample purified by normal phase chromatography on silica (Si) (0-50% ethyl acetate-cyclohexane gradient). The appropriate fractions were combined and evaporated in vacuo to give the title product, 670 mg, as an off-white solid. LCMS (2 min, formic) Rt 0.98 min, m/z (ES+) 303 (M+H).
