2,4-Dinitrotoluene → 2-(2,4-Dinitrobenzylidene)-1-methylpyrrolidine

Participants

Reaction Steps

Stir 7.0 g of 2,4-dinitrotoluene and 9.65 g of 2,2-diethoxy-1-methylpyrrolidine for 5 hours at 40° in 50 ml of benzene. Allow the resulting reaction mixture to cool to ambient temperature. Filter off the precipitate and wash it with a little benzene and hexane to obtain 3.5 g of the title compound (m.p. 188° to 190°) in the form of black-violet crystals.
