Procedure

A solution of 34.3 g. of 2-nitrotoluene in a mixture of 37 g. of N,N-dimethylformamide diethylacetal and 100 ml. of dimethylformamide was heated under reflux for 26 hours. The dark reaction mixture was concentrated by first removing the lower boiling components on a rotary evaporator and then distilling the unreacted 2-nitrotoluene at about 75°/0.2 mm. The residual dark, red liquid (35 g., 72%), which was trans-β-dimethylamino-2-nitrostyrene, was used directly in the experiments below without further purification.
