Reaction Steps

A mixture of 0.200 g (0.709 mmol) of 2,6-dibromo-3-nitropyridine, 0.121 g (0.709 mmol) of piperazin-1-yl-acetic acid ethyl ester, and 0.020 mL (1.4 mmol) of triethylamine in ethanol (3 mL) is stirred overnight at room temperature. The mixture is concentrated under reduced pressure and purified by flash silica gel chromatography to provide 0.200 g (75.7%) of (6′-bromo-3′-nitro-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-acetic acid ethyl ester as a yellow oil.
