Versuchsvorschrift

1-Methyl-5-(4-nitro-phenyl)-1H-tetrazole (470 mg), 20% Pd(OH)2 (94 mg), and 1:1 MeOH/EtOAc (25 ml), were hydrogenated at 50 PSI for 1 hour. The reaction was filtered through fiberglass filter paper under nitrogen. The filtrate was stripped to yield 383 mg of yellow solids as product. Mass Spec detects 176 (M+H). NMR (300 MHz, CDCl3) δ 7.57 (d, 2H, J=7 Hz), 6.80 (d, 2H, J=7 Hz), 4.14 (s, 3H), 4.03 (M, 2H).
