실험 절차

2-(3-Fluoro-4-methoxy-phenyl)-6-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.43 g, 0.8 mmol) was dissolved in MeOH and treated with concentrated HCl (0.25 mL, 8 mmol). The reaction mixture was heated at 100° C. for 4 hr. The solution was cooled to room temperature and the resultant precipitate was filtered, washed with MeOH and concentrated under reduced pressure to provide the corresponding 2-(3-Fluoro-4-methoxy-phenyl)-6-(4-methoxy-phenyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.24 g, 0.61 mmol) as yellow solid in 76% yield.
