Dodecylamine → HCID 178443235, compound

Participants

Reaction Steps

A solution of 2-[(5-dimethylaminomethyl-2-furyl)methylthio]ethylamine (2.41 g; 11.2 mmoles) in 25 ml of methanol was added dropwise to a well stirred cold suspension of 3,4-dimethoxy-1,2,5-thiadiazole 1,1-dioxide (2.0 g; 11.2 mmoles) in 200 ml of methanol. After stirring at 2°-5° for 15 minutes, a solution of dodecylamine (4.15 g; 22.4 mmoles) in 25 ml of methanol was added all at once, and stirring was continued at ambient temperature for 18 hours. The reaction mixture was filtered and evaporated under reduced pressure, and the residue placed on 60 g of silica gel and chromatographed using a gradient elution of methylene chloride-methanol. The appropriate fractions were combined, evaporated and the residue was rechromatographed on 60 g of silica gel using a gradient elution of acetonitrile-methanol. The appropriate fractions from the second chromatography were combined, concentrated under reduced pressure and the crystallized product was collected by filtration and dried to give 2.13 g of the title compound, mp 136°-139°.
