Synthetic Route of 763114-26-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 763114-26-7, Name is 2-Fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid,introducing its new discovery.
A aurar handkerchief nepal pharmaceutical intermediates (by machine translation)
The present invention provides a method for preparing aurar handkerchief nepal pharmaceutical intermediates, in particular relates to the technical field of pharmaceutical intermediates, S1, the O carboxybenzaldehyde, triethylamine and dichloromethane mixing and stirring, and then adding phosphorous acid dimethyl ester, the reaction at room temperature, adding methyl sulfonic acid, the reaction solution concentrated to dry, and adding water, filtering, petroleum ether to obtain white solid beating; S2, the S1 obtained in step solid, 3 – cyano – 4 – fluorophenyl formaldehyde and methylene chloride mixed, cooling, dropping triethylamine reaction, the reaction solution concentrated to dry, and adding water, filtering, methyl tert-butyl ether beating obtained white solid; S3, the S2 obtained in step solid and water mixing, cooling, adding hydrazine hydrate reaction, then adding acetone, adding NaOH aqueous solution reaction, cooling to room temperature, extraction, adjusting the pH value, separating white solid, filtering, cold water rinse, re-crystallization, to obtain white solid. The invention can improve the yield, and reduces the production cost, and easy operation. (by machine translation)
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 763114-26-7, and how the biochemistry of the body works.Synthetic Route of 763114-26-7
