5-(3-nitrophenyl)tetrazole → HCID 178507542, 화합물

참여 물질

반응 단계

5-(3-Nitrophenyl)-1H-tetrazole (4.41 g) was hydrogenated in ethanol (50 ml) over 10% palladium on carbon (0.4 g) under 3 atmospheric pressure of hydrogen at ambient temperature. The reaction mixture was filtered through Celite® (Johns Manville) and washed with ethanol. The filtrate and the washings were combined and evaporated to give 5-(3-aminophenyl)-1H-tetrazole as a crystalline powder, which was triturated in diisopropyl ether and collected by filtration to afford the desired product as a white powder (3.19 g, 85.8%). This was used in a following reaction without further purification.
