Reaction of a-aminoacetophenone oximes (2) with ethyl 6-amino-4-chloro-5-nitropyridine-2- carbamate (1) gave ethyl 6-amino-5-nitro-4-[(2-0~ 0-2-phenylethyl) amino] pyridine-2- carbamate oximes (3), which were hydrolyzed under acidic conditions to give the corresponding ketones (4). Related pyridines substituted with a keto side chain were prepared from 1 and 1, 3-diaminopropanone oximes and by oxidation of the side-chain ...
