Reaction Steps

12.0 g 2-Amino-3-bromo-5-nitropyridine, 1.93 g dichlorobis(triphenyl-phosphine)palladium(II) and 0.524 g copper(I) iodide were dispersed under nitrogen in 60 ml dry tetrahydrofuran (THF). 7.03 g trimethylsilylacetylene and 16.71 g triethylamine were added and the mixture was stirred 16 hours (hrs) at room temperature (RT). The mixture was filtered, the filtrate was evaporated and the residue purified by chromatography on silica in ethyl acetate/heptane mixtures.
