Reaction Steps

(4-Nitro-phenyl)-{4-[4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl]-phenyl}-amine (0.25 g, 0.5 mmol) was dissolved in MeOH and treated with concentrated HCl (0.16 mL, 5 mmol) and iron powder (0.34 g, 6.0 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 N-[4-(4,7-Dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl)-phenyl]-benzene-1,4-diamine (0.14 g, 0.4 mmol) as yellow solid in 80% yield.
