A 20% hydrobromic acid-ethanol solution (204 μl, 0.505 mmol) was added to an acetonitrile solution (350 ml) of 2-{4-amino-2-[(3-chloro-4-methoxy-5-methylpyridin-2-yl)methyl]-2,7-dihydro-6-thia-1,2,3,5-tetraazabenzo[cd]azulen-8-yl}-N-methylacetamide (250 mg, 0.561 mmol) at room temperature. The resulting mixture was stirred for 3 hours, and the precipitated solid was then collected by filtration. Ethanol (3 ml) was added to the resulting solid, and the resulting mixture was then stirred for 1 day. Thereafter, the solid was collected by filtration. The solid was then dried under reduced pressure at room temperature for 2 days, so as to obtain the title compound (128 mg, 0.243 mmol).
