실험 절차

2-(3,4-Dimethoxy-phenyl)-6-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.39 g, 0.7 mmol) was dissolved in MeOH and treated with concentrated HCl (0.22 mL, 7.3 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-(3,4-Dimethoxy-phenyl)-6-(4-methoxy-phenyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.25 g, 0.62 mmol) as white solid in 88% yield.
