Reaction Steps
A mixture of 90 parts of 4-chloro-3-nitropyridine, 71 parts of 4-fluorobenzenemethanamine, 63 parts of sodium carbonate and 900 parts of N,N-dimethylacetamide was stirred for 1 hour at 50° C. Water was added and the product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 106 parts (75%) of N-[(4-fluorophenyl)methyl]-3-nitro-4-pyridinamine; mp. 136.8° C. (intermediate 1).
