N,N-Dimethylethylenediamine → N-(2-Dimethylaminoethyl)-3,5-Dinitrobenzenesulfonamide Hydrochloride

Participants

Reaction Steps

A solution of 3,5-dinitrobenzensulfonyl chloride (4.6 g, 17.3 mmol) in dry tetrahydrofuran (130 mL) was added oer 50 min. to a cooled, stirred solution of N,N-dimethyl ethylenediamine (4.0 mL, 34.6 mmol) in tetrahydrofuran (100 mL). After stirring at room temperature overnight, tetrahydrofuran was removed under reduced pressure and the residue flash chromatographed over silica gel. The sulfonamide (5.1 g) was eluted with 5% methanol- 95% chloroform and purified as the hydrochloride salt, mp 238°-40°.
