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 (0.76 g, 1.5 mmol), 3-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridine (0.3 g, 2.3 mmol), Na2CO3 (2 M, 3.7 mL), and Pd(PPh3)2Cl2 (14.6 mg, 0.012 mmol) in toluene/ethanol (1:1, 10 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-pyridin-3-yl-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene as brown solid in 65% yield.
