Procedure

To a stirred and cooled (0° C.) solution of 8.7 parts of N-[(4-fluorophenyl)methyl]-4-nitro-3-pyridinamine, 1-oxide and 150 parts of trichloromethane was added dropwise a solution of 10.2 parts of phosphor trichloride in 75 parts of trichloromethane. Upon completion, the mixture was allowed to reach room temperature and stirring was continued for 1 hour at reflux temperature. The reaction mixture was cooled and the solvent was evaporated. The residue was stirred in trichloromethane. The product was filtered off and dried, yielding 9 parts of N-[(4-fluorophenyl)methyl]-4-nitro-3-pyridinamine monohydrochloride (intermediate 17).
