Procedure

Ethanol (36.7 L) was added to 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 (1.07 kg, 2.28 mmol), and the resulting mixture was then stirred at 25° C. Thereafter, 1 M hydrochloric acid (2.06 L, 2.06 mol) was added to the reaction mixture over 55 minutes. Then, concentrated hydrochloric acid (57 ml, 0.68 mol) was further added to the reaction mixture over 33 minutes, and the resulting mixture was then stirred for 30 minutes. Thereafter, concentrated hydrochloric acid (191 ml, 2.29 mol) was added to the reaction mixture over 11 minutes, and the resulting mixture was then stirred for 1 hour. The reaction mixture was cooled to 5° C. over 76 minutes. Twenty-two hours later, the precipitated crystal was filtrated, was then washed with ethanol (5 L), and was then dried under reduced pressure at 40° C. for 18 hours, so as to obtain the above title compound (1.05 kg, 2.18 mol). Yield: 95%.
