Reaction Steps

2-[(2,5-dimethylphenyl)oxy]-5-nitropyridine (Intermediate 33, 140 mg, 0.450 mmol) was dissolved in ethanol (3 mL). Hydrazine hydrate (83 μL, 0.884 mmol) and palladium on carbon (47 mg, 0.044 mmol) were added. The reaction mixture was heated at reflux under argon. After overnight heating, the reaction was cooled down. The reaction mixture was filtered. The organic phase was evaporated under vacuum. The residue was purified by SCX (wash with MeOH, desorbed with 2N methanolic ammonia). Evaporation afforded the title compound (85 mg).
