Procedure

A diethyl ether solution (50 ml) of methanesulfonic acid (32 mg, 0.302 mmol) was added at 5° C. to an acetonitrile solution (150 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 (151 mg, 0.339 mmol). The resulting mixture was stirred at 5° C. for 25 minutes. Thereafter, the solvent was distilled away under reduced pressure, an appropriate amount of diethyl ether was then added to the residue, and a solid was then collected by filtration. Thereafter, ethanol (1 ml) was added to the resulting solid, and the resulting mixture was then stirred at room temperature for approximately 1 day. Thereafter, a solid was collected by filtration, and it was then dried under reduced pressure at room temperature for 1 day, so as to obtain the title compound (145 mg, 0.268 mmol).
