Reaction Steps

A suspension of 350 mg of 2-amino-6-chloro-3-nitropyridine, 744 mg of N-(tert-butoxycarbonyl)piperazine and 552 mg of potassium carbonate in 4 ml of N-methylpyrrolidone was stirred in nitrogen atmosphere for 15 minutes at 160° C. The suspension was cooled to room temperature, to which 10 ml of water was added. Whereupon formed solid was recovered by filtration, washed with hexane and dried to provide 323 mg of the title compound.
