Procedure

The pyridine derivative of the present invention is represented by the general formula A or B. For example, 50 g of 2-chloro--5-nitropyridine and 150 ml of diethylamine were placed in a sealed tube and heated at 120° C. for 7 hr. Pure water was added to the precipitated crystal, and the crystal was collected by filtration and recrystallized from 300 ml of methanol to give 53 g of 2-diethylamino-5-nitropyridine (yield: 86%, melting point: 75° to 76° C.).
