Reaction Steps

A mixture of the corresponding intermediate 6-(4-Bromo-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (1.46 g, 3.2 mmol), trans-beta-Styreneboronic acid (0.7 g, 4.9 mmol), Na2CO3 (2M, 7 mL), and Pd(PPh3)2Cl2 (300 mg, 0.26 mmol) in toluene/ethanol (1:1, 20 mL) was heated at 100° C. for 8 hr. The solution was cooled to room temperature and extracted with ethyl acetate. The target product was purified by gravity column chromatography (30% EtOAc in hexane) to give 6-(4-Styryl-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene as yellow solid in 68% yield.
