Reaction Steps
A mixture of 5-(2,2-dibromovinyl)-2-methylpyridine (0.10.9 g, 0.00393 mol), potassium tertbutoxide (0.88 g, 0.00787 mol) and toluene (13 mL) were heated at 80° C. for 4 h. After completion of reaction, the reaction mixture was cooled to RT, diluted with water (15 mL), and extracted with EtOAc (3×50 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduce pressure to obtain product as a yellow oil (0.25 g, 32.4%).
