Reaction Conditions

Reaction Steps

In a 50 mL round-bottomed flask 2-[(2-ethylphenyl)oxy]-5-nitropyridine (Intermediate 45, 623 mg) was dissolved in ethanol (10 mL) to give a pale orange solution. Palladium on carbon (244 mg, 0.230 mmol) and hydrazine hydrate (0.442 mL, 4.59 mmol) were added. The reaction mixture was stirred at 90° C. After 3 hours the reaction was completed. The reaction mixture was filtered and the organic phase was evaporated under vacuum affording 1.1408 g of a dark orange solid that was charged on a 10 g SCX cartridge. It was then flushed with 200 mL of ethanol followed by 50 mL of 2M solution of ammonia in MeOH. The ammonia eluate was evaporated under vacuum to afford the title compound as dark orange solid (456.1 mg).
