Reaction Steps

6-[4-(4-Methyl-piperazin-1-yl)-phenyl]-2-pyridin-3-yl-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.45 g, 0.8 mmol) was dissolved in MeOH and treated with concentrated HCl (0.25 mL, 8 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 6-[4-(4-Methyl-piperazin-1-yl)-phenyl]-2-pyridin-3-yl-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene hydrochloride (0.2 g, 0.44 mmol) as yellow solid in 55% yield.
