Procedure

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 (0.75 g, 1.5 mmol), 1-Methyl-4-[5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-2-yl]-piperazine (0.5 g, 17 mmol), Na2CO3 (2 M, 3.6 mL), and Pd(PPh3)2Cl2 (110 mg, 0.15 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 6-(4-Methoxy-phenyl)-2-[6-(4-methyl-piperazin-1-yl)-pyridin-3-yl]-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene as orange solid in 60% yield.
