Reaction Steps
A mixture of 2-methyl-5-(4-nitro-phenyl)-2H-tetrazole (0.260 g, 1.27 mmol) and palladium on charcoal (53.6 mg) in ethanol (50 mL) is stirred in high pressure reactor under H2 at 4 bars for 17 hours. The catalyst is removed by filtration through Celite 521, washing with EtOH. The filtrates are combined and concentrated in vacuo to afford the title compound as a white solid (0.213 g, 96%). HPLC (254 nm) 1.50 min (89%)
