Reaction Steps

3-{4-[4-(2-Trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl]-phenylamino}-phenol (0.24 g, 0.5 mmol) was dissolved in MeOH and treated with concentrated HCl (0.16 mL, 5 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 3-[4-(4,7-Dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl)-phenylamino]-phenol (0.15 g, 0.44 mmol) as yellow solid in 88% yield.
