2-Nitro-5-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,3-triazol-4-yl)phenyl]thiophene-3-carboxamide → 2-Amino-5-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,3-triazol-4-yl)phenyl]thiophene-3-carboxamide

Participants

Reaction Steps

To a solution of 2-nitro-5-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,3-triazol-4-yl)phenyl]thiophene-3-carboxamide (440 mg, 0.99 mmol) in MeOH (15 mL) was added 3% Pt/C doped with 0.6% V (64 mg, 9.9 μmmol). The reaction was stirred under a hydrogen balloon at room temperature overnight. The solution was diluted with MeOH and DMF, filtered through Celite, and evaporated. The crude was triturated with MeOH and filtered to isolate the title compound as a gray solid. The mother liquor was concentrated, triturated with CH2Cl2, and filtered to isolate additional product.
