Abstract: | 1-Oxides of 4-nitro-3-pyridinecarboxylic acid (3) and methyl 4-methoxy-3-pyridinecarboxylate (5) were converted to 4-(diphenylmethyl)amino (7), 4-phenylthio (8), 4-phenylamino (9) and 4-(2-methylpropyl)-amino (6) derivatives by reaction with the corresponding nucleophiles. The 4-phenylamino derivative 9 was alkylated with bromoethane to form the corresponding ethyl ester of the 1-ethoxypyridinium salt 10. |
