Malinowski, Marek published the artcileTitanium(0) reagents. III. A convenient preparation of 4-pyridinamine derivatives, HPLC of Formula: 18437-58-6, the publication is Journal fuer Praktische Chemie (Leipzig) (1988), 330(1), 154-8, database is CAplus.
Ti(0) slurry, easily accessible by the reduction of TiCl4 with LiAlH4 or Mg in THF, is an excellent reagent for the reduction of N-nitropyridine N-oxides, e.g., I (R = H, Me, F, Cl) to 4-aminopyridines, e.g., II. The reaction proceeds smoothly and fast at room temperature giving the amines in >90% yields.
