Dimethylamino-ethenyl

In 1-substituierten Nitro-imidazolen konnen 2-, 4- oder 5-Methyl-Gruppen mit Dialkoxy-dimethylamino-methan (z. B. Dimethoxy-dimethylamino-1074, Dicyclohexyloxy-dimethylami-no-1073, Bis-[dimethylamino]-tert.-butyloxy-methan1143) zu 2-, 4- oder 5-(2-Dimethylamino-ethenyl)-Gruppen umgesetzt werden. Auf diese Weise konnen z. B. 5- (2-Dime thy lamino-ethe-nyl)-l-methyl-4-nitro-101A und 2- (2-Dimethylamino-ethenyl)-1 -methyl-5-nitro-imidazol1013,1143 (weitere Beispiele s.1143) hergestellt werden. [Pg.179]

Benzoylamino-6 -pyrido[l,2-a]pyrimidin-6-one 224 was prepared starting from 2-methylpyrimidine and N.TV-dimethylformamide dimethyl-acetate in boiling dimethylformamide (91BSB533). Then the resulting 2-[( )-2-(N,N-dimethylamino)ethenyl)]pyrimidine was reacted with 2-phenyl-5(4//)-oxazolone in refluxing acetic acid to give 6-oxopyrido-[l,2-a]pyrimidine 224 in 33% yield. [Pg.159]
