Patent number: 8399663Abstract: Anytime obtained is uniform crystal of N-(4-fluorophenyl)-N?-phenyl-N?-(pyrimidin-2-ylmethyl)-1,3,5-triazine-2,4,6-triamine (compound A) and/or N,N?-bis (4-fluorophenyl)-N?-(pyrimidin-2-ylmethyl)-1,3,5-triazine-2,4,6-triamine (compound B) as a medicament or a starting material for the preparation of the medicament, and provided are a fumarate of the compound A and/or the compound B having excellent stability and a novel crystal thereof. A salt of the compound A and/or the compound B with fumaric acid enables uniform crystal to be anytime obtained, and thus, it is a compound that is very useful as a medicament or a starting material for the preparation of the medicament having excellent stability.Type: GrantFiled: April 2, 2010Date of Patent: March 19, 2013Assignee: Astellas Pharma Inc.Inventors: Junya Ohmori, Makoto Kasai, Takenori Kimura, Noritaka Hamada, Ryo Mizoguchi, Satoshi Miyamoto, Noriyuki Kawano

Patent number: 8278333Abstract: Object Provided are ?-form crystal, ?-form crystal, and ?-form crystal of a benzoxadiazole derivative, wherein a uniform crystal having sufficient qualities can be obtained with high reproducibility, and they can be anytime supplied as crystals of drug substance for use in producing pharmaceuticals, are particularly suitable for mass synthesis in industrial production, hardly exhibit hygroscopicity and have particularly excellent photo-resistance. Means for Resolution A solving means includes ?-form crystal of 4-[3-isopropyl-5-(6-phenyl-3-pyridyl)-4H-1,2,4-triazol-4-yl]-2,1,3-benzoxadiazole, which shows an endothermic peak at 145 to 150° C. according to a differential scanning calorimeter analysis (DSC analysis) and shows X-ray powder diffraction peaks at 9.8, 11.1, 12.8, 13.3, 17.1, 20.2, 21.2 and 22.3 in 2?(°), and the like.Type: GrantFiled: July 13, 2007Date of Patent: October 2, 2012Assignee: Astellas Pharma Inc.Inventors: Noritaka Hamada, Ryo Mizoguchi, Kuniyuki Sano, Takaaki Sakaida, Yuji Awamura, Yu Iwakawa, Takahiko Tobe, Takashi Sugane
