Versuchsvorschrift

In a similar manner, N-{5-amino-4-[(3-fluorophenyl)hydrazono]4H-pyrazol-3-ylmethyl}nicotinamide was prepared by reacting 5-aminomethyl-4-[(3-fluorophenyl)hydrazono]-4H-pyrazol-3-ylamine (60 mg, 0.25 mmole) with nicotinoyl chloride hydrochloride (46.3 mg, 0.26 mmole). The reaction was worked up by the addition of saline and ethyl acetate. The crude material was purified by preparative TLC (CH2Cl2:MeOH=9:1) to yield 36 mg (41%) of the title compound as a yellow powder. MS (m/z, ES+): 340 (M+1, 100%); 1H NMR (ppm, 300 MHz, DMSO-d6) δ 11.80 (br s, 1H), 9.01 (br s, 2H), 8.70 (d, 1H), 8.20 (d, 1H), 7.30-7.70 (m, 4H), 6.85-7.25 (m, 3H), 4.70 (br s, 2H).
