YieldReaction ConditionsOperation in experiment
80% With ammonium formate In methanol at 55℃; for 16 h; 4-Amino-3-trifluoromethoxy pyridine (21); At 25 0C, palladium (10percent on charcoal, 470 mg) was added with stirring to a solution of 4-amino-2-chloro-3-trifluoromethoxypyridine (20, 1.5 g, 7.0 mmol) and ammonium formate (880 mg, 14.0 mmol, 2 eq) in methanol (12 mL). The reaction mixture was stirred for 16 h at 55 0C before being filtrated under suction and the solvent evaporated. The residue was partitioned between ethyl acetate (2χ 20 mL) and water (30 mL). The combined organic layers were dried over sodium sulfate before being evaporated. The crude yellow oil was distilled under vacuum to afford pure 4-amino-3-trifluoromethoxy pyridine (21, 1.0 g, 5.6 mmol, 80percent) as a colorless oil; b.p 110-114 0C / 14 mbar.1H NMR (CDCl3, 300 MHz): δ = 8.19 (s, 1 H), 8.05 (d, J= 5.5 Hz 1 H), 6.59 (d, J= 5.5Hz, 1 H), 4.41 (bs, 2 H). - 19F NMR (CDCl3, 282 MHz): δ = -58.7. - 13C NMR (CD3OD, 75 MHz): δ = 150.8, 148.5, 143.5, 132.9, 120.8 (q, J = 259 Hz), 110.4. - C6H5F3N2O (178): calcd.
