Procedure

6 ml of a 2M solution of dimethylamine in tetrahydrofuran are added to a solution of 1 g of 5-bromo-2-nitropyridine in 5 ml of ethanol. The reaction mixture is heated at 140° C. for 2 hours in a microwave device. After cooling, the solid formed is separated off and washed with ethyl ether to give 850 mg of N,N-dimethyl-6-nitropyridine-3-amine in the form of a yellow solid.
