Reaction Steps

2-{[3-(1-methylethyl)phenyl]oxy}-5-nitropyridine (Intermediate 23, 1.39 g) was dissolved in ethanol (25 mL). Hydrazine monohydrate (0.524 mL, 1076 mmol) and palladium on carbon (401 mg, 0.377 mmol) were added. The reaction mixture was heated at reflux under argon for 1 hour. The reaction was cooled down and then filtered on celite. The organic phase was evaporated under vacuum. The residue was purified by flash chromatography on silica (Companion instrument, 120 g silica cartridge, gradient cyclohexane/ethylacetate from 100/0 to 30/70 in 15 min then 30/70 during 30 min). Evaporation afforded the title compound as a yellow oil (821 mg).
