Reaction Steps

1-(3,4-dichlorophenylsulfonyl)-2,5-dimethylpiperazine (1.04 g, 3.22 mmol), 2,3-dichloropyridine (476.5 mg. 3.22 mmol), diisopropylethylamine (1.4 mL, 8.05 mmol) and DMF (1.2 mL) were charged to a microwave vial and the mixture was irradiated at 200° C. for 1 hour. Reaction was complete as determined by TLC. The reaction mixture was diluted with ethyl acetate and washed with water. After solvent evaporation crude product was purified with flash column chromatography to yield 1-(3-chloropyridin-2-yl)-4-[(3,4-dichlorophenyl)sulfonyl]-2,5-dimethylpiperazine in 2% yield (27.1 mg) as yellow solid.
