실험 절차

With cooling with ice, triethylamine (0.57 ml, 4.06 mmol) and N,N,N′-trimethylethane-1,2-diamine (0.30 ml, 2.23 mmol) were added to a tetrahydrofuran solution (5 ml) of 5,6-dichloropyridine-3-sulfonyl chloride (500 mg, 2.03 mmol) obtained in the above reaction, and stirred for 5 minutes. Saturated saline water was added to the reaction solution, extracted with chloroform, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by amine-type silica gel column chromatography (Biotage NH, hexane:ethyl acetate=5:1 to 3:1) to obtain 5,6-dichloro-N-[2-(dimethylamino)ethyl]-N-methylpyridine-3-sulfonamide (460 mg, yield: 73%) as a red solid.
