Reaction Steps

In a 50 mL round-bottomed flask 2-(4-methylchroman-5-yl)oxy-5-nitro-pyridine (Intermediate 212, 22.9 mg, 0.08 mmol) was dissolved in Ethanol (10 mL) to give a pale yellow solution. Pd/C (17.88 mg, 0.017 mmol) and hydrazine hydrate (0.4 mL, 4.15 mmol) were added. The reaction mixture was stirred at 90° C. The reaction mixture was filtered and evaporated in vacuo to give the title compound (22.9 mg) as a pale yellow oil.
