実験手順

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 (0.87 g, 1.8 mmol), 2-(4-Fluoro-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (0.4 g, 2.7 mmol), Na2CO3 (2 M, 4.3 ml), and Pd(PPh3)2Cl2 (170 mg, 0.14 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 2-(4-Fluoro-phenyl)-6-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene as brown solid in 66% yield.
