90 °C

A mixture of 9.7 parts of 4-fluorobenzenemethanamine hydrochloride, 9.4 parts of 2-chloro-3-nitropyridine, 10.6 parts of sodium carbonate, 0.1 parts of potassium iodide and 90 parts of N,N-dimethylformamide is stirred for 1 hour at 90° C. The reaction mixture is cooled and poured onto water. The precipitated product is filtered off and crystallized from 2-propanol, yielding 10.5 parts (71%) of N-(4-fluorophenylmethyl)-3-nitro-2-pyridinamine; mp. 76° C.
