A mixture of 3.6 g (0.01 mol) N1 methyl-3,5-dinitro-N4,N4 -dipropylsulfanilamide, 2.2 g (0.02 mol) ethyl chloroformate, 2.8 g (0.02 mol) potassium carbonate, and 50 ml dimethoxyethane was heated at reflux until gas evolution ceased. The reaction mixture was filtered and evaporated under reduced pressure. The residue was recrystallized from ethanol to give 2.5 g of the product, m.p. 104°C (dec.).
