To a 250 milliliter (mL) round-bottomed flask containing hydrazine hydrate (64% aqueous (aq) solution; 7.27 mL, 15.0 millimoles (mmol)) in EtOH (100 mL) at 80° C. was added 4-[1-(4-trifluoromethoxyphenyl)-1H-[1,2,4]triazol-3-yl]-benzaldehyde (5.00 grams (g), 1.50 mmol) portionwise over 5 minutes (min) The solution was stirred at reflux for an additional 3 hours (h) before being diluted with water (H2O; 300 mL) and cooled to 0° C. The precipitated product was collected by vacuum filtration as a white solid (4.89 g, 93%): mp 222-226° C.; 1H NMR (400 MHz, DMSO-d6) δ 8.59 (s, 1H), 8.22 (d, J=8.2 Hz, 2H), 7.84-7.79 (m, 3H), 7.66 (d, J=8.3 Hz, 2H), 7.41 (d, J=8.2 Hz, 2H), 7.29 (s, 1H), 5.63 (br s, 2H); ESIMS m/z 348 (M+H).
