Nucleophilic amination–defluorination reaction of the 6,7-difluoro derivative of 3-amino-2-methyl-3H-quinazolin-4-one has been established to occur at position 7, as shown by X-ray crystallographic analysis. -------------------------------------------------------------------------------- Доп.точки доступа: Nosova, E.
