Reaction Steps

Cyclopropylacetylene (73.7 μL), copper iodide (3.16 mg) and tetrakis(triphenylphosphine)palladium (9.59 mg) were added to a solution of ethyl 5-bromopyridine-2-carboxylate (95.5 mg) in diisopropylamine (2 mL) at room temperature, and the mixture was stirred at room temperature for 17 hours and five minutes. The reaction solution was concentrated under reduced pressure. The residue was purified by NH-silica gel column chromatography to obtain the title compound (19.4 mg).
