Reaction Steps

A mixture solution of 2,6-dinitrotoluene (18.2 g, 0.1 mol) and N,N-dimethylformamide dimethylacetal (28 mL, d=0.89, 0.2 mol) in anhydrous DMF (80 mL) was refluxed for 5 h. The mixture was then evaporated to concentrate to a reddish-black oil. After run flash column using CH2Cl2:MeOH (10:1) as eluent to give a red crystalline solid intermediate, 2,6-dinitro-trans-{circumflex over (α)}-dimethylaminostyrene (20.5 g, yield 86%).
