Procedure

In a 50 mL round-bottomed flask 2-[(2,3-dimethylphenyl)oxy]-5-nitropyridine (Intermediate 37, 640 mg) was dissolved in ethanol (10 mL) to give a pale yellow solution. Hydrazine hydrate (0.463 mL, 4.72 mmol) and palladium on carbon (25.10 mg, 0.236 mmol) were added. The reaction mixture was stirred at 90° C. After 1 hour, the reaction was complete. The reaction mixture was filtered and the organic phase was evaporated in vacuo affording the title compound as a pale yellow oil (573 mg).
