Versuchsvorschrift
A solution of ethyl 2-(3-(5-amino-3-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)acetate (3 g, 9.58 mmol) in conc. NH4OH (40 mL) was heated at reflux for 2 h. After removal of the solvent, the residue was purified by column chromatography to afford 2-(3-(5-amino-3-(trifluoromethyl)-1H-pyrazol-1-yl)phenyl)acetamide (1.8 mg, 66% yield). 1H NMR (300 MHz, DMSO-d6): 7.48-7.42 (m, 4H), 7.30 (s, 1H), 6.91 (s, 1H), 5.77 (s, 1H), 5.73-5.72 (m, 2H), 4.44 (s, 2H). MS (ESI) m/z: 285 (M+H+).
