Reaction Steps

2,6-Bis-(4-methoxy-phenyl)-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.11 g, 0.2 mmol) was dissolved in MeOH and treated with concentrated HCl (0.06 mL, 2.0 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 2,6-Bis-(4-methoxy-phenyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.08 g, 0.19 mmol) as white solid in 95% yield.
