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 (0.95 g, 1.9 mmol), 3-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylamine (0.34 g, 1.1 mmol), Na2CO3 (2 M, 4.6 mL), and Pd(PPh3)2Cl2 (226 mg, 0.1 mmol) in toluene/ethanol (1:1, 16 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 3-[6-(4-Methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-2-yl]-phenylamine as brown solid in 67% yield.
