YieldReaction ConditionsOperation in experiment
With palladium 10% on activated carbon; hydrogen; In methanol; at 25℃; under 760.051 Torr; Example 4 (0055) Catalytic hydrogenation of 3-fluoro-4-nitropyridine N-oxide (9): 0.1 mg of 3-fluoro-4-aminopyridine N-oxide (9) was dissolved in 4 mL of MeOH in a 50 mL round bottom flask containing a stir bar. While stirring, 3-4 mg of 10percent Pd/C (dry basis) was added and the flask sealed with a rubber septum. The vial was evacuated and backfilled with hydrogen gas from a balloon and the mixture was allowed to react for 10 min. After 10 min, the suspension was passed through a 0.4 m PTFE filter and analyzed by HPLC (conditions C). Reference retention times: 3-fluoro-4-aminopyridine N-oxide (9)=5.80 min, 3-fluoro-4-aminopyridine (10)=7.05 min. Retention time for the product matched within 0.05 min the reference standard. Identity of the product was confirmed by HR-MS (m/z M+ exp.: 112.0416, calc: 112.0437). Product amount was calculated from the area under the curve of the HPLC UV2 trace using a calibration curve.

YieldReaction ConditionsOperation in experiment
With ammonium hydroxide; In water; EXAMPLE 20 Preparation of 4-Amino-3-fluoropyridine (3-4) 3-Fluoro-4-nitropyridine N-oxide (3-3) (1.0 g, 6.29 mmol) and FeSO4.H2O (15 g, 37.5 mmol) were suspended in water. Approximately 14 mL of NH4OH was added until a dark color persisted. The resulting mixture was heated to 90° C. for 1 hour under a steady stream of nitrogen. The reaction mixture was allowed to cool to ambient temperature. It was then extracted with 20 mL of diethyl ether (4*), dried with anhydrous sodium sulfate, and concentrated in vacuo to yield the title compound 468 mg (66percent) as a brown oil which crystallized upon standing; the product was verified by NMR. 1H NMR (CDCl3): delta 8.18 (d, 1H), 8.03 (d, 1H), 6.65 (t, 1H), 4.3 (br, 2H).
