PROCESS FOR PREPARING 2-AMINO-3-NITRO-6-(4-FLUOR-BENZYL-AMINO)-PYRIDINE AS WELL AS 2-AMINO-3-(CARBETOXY-AMINO)-6-(4-FLUOR-BENZYL-AMINO)-PYRIDINE

摘要

There is described a process for the production of 2-amino-3-nitro-6-(4-fluorobenzylamino)-pyridine which consists essentially of reacting 2-amino-3-nitro-6-methoxypyridine with 4-fluorobenzylamine in water at elevated temperature; in a given case the nitro group can be subsequently reduced and a carbethoxy group introduced.
