摘要:
The present invention relates to novel crystalline polymorphic and amorphous forms of the compound methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl}-3-methoxy-acrylate (azoxystrobin). Infrared Raman spectra, X-ray powder diffraction pattern and differential scanning calorimetry thermogram of two polymorphs "A" and "B" are provided. Further, the present invention also provides methods for preparing the novel polymorphic forms "A" and "B", as well as processes for producing mixtures of the polymorphs, and a process for preparing amorphous azoxystrobin. Yet further, the present invention provides anti-fungal compositions comprising the novel crystalline polymorphs "A" and "B" or amorphous azoxystrobin, which are useful for controlling and combating fungi grown on agricultural and horticultural crops and up-land, and methods of using the same as pesticidal agents for combating fungi on agricultural and horticultural crops.
摘要:
The present invention relates to an improved process for the synthesis and purification of 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-a,a,a-trifluoro-2,6-dinitro-p-toluidine (fluazinam) and other pyridinamines, which implements methyl isobutyl ketone (MIBK) as the reaction solvent. The process of the invention overcomes the drawbacks of prior art methods, by reducing the side reactions such as hydrolysis, eliminating the need for difficult and labor-intensive purification methods, and providing pure products in higher yields. The present invention relates to novel crystalline polymorphic forms fluazinam, and to mixtures of the polymorphs. The present invention also provides methods for preparing the novel polymorphs, as well as pharmaceutical compositions comprising same, and methods of using the polymorphs as pesticidal agents for combating noxious living organisms on agricultural and horticultural crops.
