To piperazine (29.0 g) dissolved at 115° C. was added 2,5-dichloropyridine (5.1 g) and the mixture was stirred at 140-150° C. for 1 hr. The reaction mixture was poured into a 1N aqueous sodium hydroxide solution and extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated to give the title compound (5.0 g) as a pale-brown solid.
