Procedure

To a flask containing 5-[3-(4-fluorophenyl)(1H-indazol-5-yl)]-3-(4-nitrophenyl)-4H-1,2,4-triazole (60 mg) was added ethyl acetate (15 ml). The flask was evacuated and purged with nitrogen. To the flask was added palladium on carbon catalyst (10 mg). The reaction was placed under a hydrogen atmosphere and allowed to stir overnight. The reaction was filtered through celite and the organic layer was concentrated. The product was purified by HPLC to yield the title compound (15 mg, 26% yield). 1H NMR (DMSO-d6) δ 13.5 (s, 1H), 8.65 (s, 1H), 8.1 (d, 1H), 8.05 (t, 2H), 7.77 (d, 2H), 7.7 (d, 1H), 7.4 (t, 2H), 6.7 (d, 2H), ES-MS (m/z) 371 [M+1]+.
