반응 단계
A stirring mixture of ethyl 6-bromoimidazo[1,2-a]pyridine-3-carboxylate (24s) (500 mg, 1.86 mmol), allyl cyanide (224 uL, 2.79 mmol), tris(dibenzylideneacetone)dipalladium(0) (26 mg, 0.028 mmol), [(t-Bu)3PH]BF4 (16 mg, 0.056 mmol), and N,N-dicyclohexylmethylamine (433 μL, 2.04 mmol) in anhydrous 1,4-dioxane (6 mL) was heated at 95° C. overnight. The reaction was cooled to room temperature and filtered. The solvent was concentrated. The crude product was purified by silica chromatography to give ethyl 6-(3-cyanoprop-1-enyl)imidazo[1,2-a]pyridine-3-carboxylate (24v). MS m/z 256.4 (M+1)+.
