A mixture of 19 parts of 2-chloro-3-nitropyridine, 13.5 parts of 2-ethoxyethanamine, 13 parts of sodium hydrogen carbonate and 240 parts of ethanol was stirred for 6 hours at reflux temperature. After cooling, the mixture was filtered over diatomaceous earth and the filtrate was evaporated, yielding 25.5 parts (100%) of N-(2-ethoxyethyl)-3-nitro-2-pyridinamine as a residue (interm. 8).
