実験手順

To a solution of 1-chloro-4-(2,2-dibromovinyl)benzene (9.60 g, 32.7 mmol) in toluene was added potassium tertbutoxide (7.35 g, 65.6 mmol) at RT. The reaction mixture was heated at 80° C. for 3 h. The reaction was monitored by LCMS and TLC. The reaction mixture was diluted with water and extracted with EtOAc. The organic was dried over sodium sulfate and concentrated under reduced pressure to give the desired product (5.5 g).
