摘要：

Provided are novel crystals of 4-bromo-6-(3-(4-chloro-phenyl)propoxy)-5-(pyridin-3-ylmethylamino)pyridazin-3(2H)-one monohydrochloride, and a process for production of same. A-form crystals of 4-bromo-6-(3-(4-chlorophenyl)propoxy)-5-(pyridin-3-ylmethylamino)pyridazin-3(2H)-one monohydro-chloride represented by formula (1), which exhibit a powder X-ray diffraction pattern with characteristic peaks at diffraction angles (2θ) of 8.24, 11.24, 11.76, 16.48, 17.16, 17.80, 18.24, 19.80, 21.64, 22.56, 22.96, 23.68, 24.52, 25.92, 26.32, 27.12, 27.40, 28.00, 28.64, 29.28, 31.84 and 34.80°.
