Ethyl Acetate → 4-(2H-1,2,3,4-tetrazol-2-yl)aniline

Participants

Reaction Steps

2-(4-Nitrophenyl)-2H-tetrazole (200 mg, 1.05 mmol) was suspended in ethanol (1 mL). Ethyl acetate (1 mL) was added to improved solubility. The solution was degassed and purged with nitrogen 3 times before palladium on carbon (10% w/w, 223 mg, 0.2 mmol) was added. The mixture was degassed and purged with hydrogen 3 times and stirred under a hydrogen balloon for 2 hours. The reaction was diluted with acetone and passed through a plug of silica gel, which was washed thoroughly with acetone. The filtrated was concentrated to give the crude product which was used as isolated.
