Procedure

After adding 1 g of 2-amino-4-(4-nitrophenoxy)pyridine to a mixture of 2.0 g of iron powder, 4.0 g of ammonium chloride, 30 ml of ethanol, 30 ml of dimethylformamide and 15 ml of water, the mixture was vigorously stirred at 100° C. for 10 minutes. The reaction solution was filtered with celite and the solvent was distilled off under reduced pressure to obtain 0.53 g of the target substance as a solid.
