Reaction Steps
In a 50 ml round-bottomed flask 2-[(3-methyl-1,3-dihydro-2-benzofuran-4-yl)oxy]-5-nitropyridine (Intermediate 99, 38.3 mg) was dissolved in ethanol (10 ml) to give a pale yellow solution. Pd/C (14.22 mg, 0.013 mmol) and hydrazine hydrate (0.026 ml, 0.267 mmol) were added. The reaction mixture was stirred at 90° C. After 45 minutes, the reaction mixture was filtered and the organic phase was evaporated under vacuum to afford the title compound (32 mg).
