Reaction Steps

To a suspension of Cu(OAc)2.H2O (1.5 g) in pyridine-methanol (1:1, 10 ml) was added N-(2-propynyl)-2,4-dinitroaniline (1.00 g, 4.52×10-1 mole). The reaction mixture was stirred at 50° C. for 30 minutes. The mixture was poured into excess water, and filtered. The crude solid was recrystallized from nitromethane to afford pale green crystals. Yield: 0.86 g (86%). The compound failed to melt at 200° C. but changed from green to bronze color at 120° C. It could be recrystallized from dioxane to give a different crystal form, appearing as orange crystals which turn deep orange at 140° C. IR (KBr): 3380 (NH), 1617, 1592, 1333 and 1312 cm-1 (Ar--NO2).
