Reaction Steps

2,5-Dibromopyridine (1 g) was heated in dimethylacetamide (2.5 ml) with ethanesulfonylpiperazine (0.752 g) and diisopropylethylamine (1.84 ml) at 120° C. for 18 h. After cooling, the reaction mixture was poured into water (30 ml) and the precipitated solid was collected by filtration. The product was purified by column chromatography eluting with dichloromethane (0.50 g).
