Reaction Steps

A mixture of the corresponding 2-Bromo-6-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.8 g, 1.7 mmol), Furan-3-boronic acid (0.28 g, 2.5 mmol), Na2CO3 (2 M, 3.9 mL), and Pd(PPh3)2Cl2 (15 mg, 0.13 mmol) in toluene/ethanol (1:1, 12 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 (20% EtOAc in hexane) to give 2-Furan-3-yl-6-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene as orange solid in 67% yield.
