Reaktionsschritte

18.21 g (0.1 mol) of 2,4-dinitrotoluene, 21.23 g (0.1 mol) of 4-benzyloxy-benzaldehyde and 1.8 mL of pyrrolidine in 140 mL of dimethylformamide were heated for 2 hours at 100° C. which caused the reaction mixture to assume a dark-brown color. The reaction mixture was then allowed to cool to room temperature after which it was diluted with 210 mL of isopropanol and allowed to agitate for an additional hour with ice cooling. The product was suction-filtered off, washed with a small amount of cold isopropanol and then dried at 40° C. under vacuum.
