Reaction Steps

To 4-[3-(ethyloxy)-4-nitrophenyl]pyridine (2.2 g, 9.0 mmol) in 80 mL of EtOH was added, 1-chloro-2,4-dinitrobenzene (14.6 g, 72.06 mmol). The mixture was heated to 102° C. for 72 h. The mixture was cooled and rotovaped down. The product was taken up in acetone. The resulting slurry was filtered and washed with acetone. The product was dried under vacuum to give the title compound of step B (3.7 g, 7.93 mmol, 92%). MS (ESI): 411 [M+H]+.
