Reaction Steps
A mixture of 4.5 g (0.0125 mol) N1 -methyl-3,5-dinitro-N4,N4 -dipropylsulfanilamide, 3.06 g (0.025 mol) n-propyl chloroformate, 3.5 g (0.025 mol) potassium carbonate, and 75 ml dimethoxyethane was heated at reflux for 2 hours. The reaction mixture was filtered and evaporated under reduced pressure. The residue was recrystallized from ethanol to give 4.5 g of the product, m.p. 110°-113°C, as an orange solid.
