Reaction Steps

4′-[4-(2-Trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl]-biphenyl-4-ol (0.06 g, 0.13 mmol) was dissolved in MeOH and treated with concentrated HCl (0.3 mL, 10 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 4′-(4,7-Dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-6-yl)-biphenyl-4-ol (0.03 g, 0.08 mmol) as brown solid in 61% yield.
