실험 절차

In a similar manner, N-{5-amino-4-[(3-fluorophenyl)hydrazono]-4H-pyrazol-3-ylmethyl}succinamic acid was prepared by reacting 5-aminomethyl-4-[(3-fluorophenyl)hydrazono]-4H-pyrazol-3-ylamine (60 mg, 0.25 mmole) with succinic anhydide (40 mg, 0.4 mmole). The reaction was worked up by the addition of aqueous ammonium chloride solution and ethyl acetate. The crude material was purified by preparative TLC (CH2Cl2:CH3OH:H2O:HOAc=210:21:1.6:0.8) to yield 45 mg (51%) of the title compound as a yellow powder. MS (m/z, ES−): 333 (M−1, 42%); 1H NMR (ppm, 300 MHz, DMSO-d6) δ 8.23 (br s, 1H), 7.35-7.63 (m, 3H), 6.83-7.20 (m, 3H), 4.42 (s, 2H), 2.33 (m, 4H).
