Reaction Steps

5-[6-[4-(4-Methyl-piperazin-1-yl)-phenyl]-4-(2-trimethylsilanyl-ethoxymethyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-2-yl]-pyridin-2-ylamine (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 5-{6-[4-(4-Methyl-piperazin-1-yl)-phenyl]-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalen-2-yl}-pyridin-2-ylamine hydrochloride (0.18 g, 0.39 mmol) as yellow solid in 49% yield.
