Participants

Reaction Steps

(3-Trifluoromethoxyphenyl)oxoacetaldehyde was reacted with 2,4-difluorobenzenecarboximidic hydrazide hydriodide salt using the method described in Example 1 to give 3-(2,4-difluorophenyl)-5-(3-trifluoromethoxyphenyl)-[1,2,4]triazine as a yellow solid (655 mg): δH (400 MHz, CDCl3) 7.01-7.12 (2H, m), 7.47-7.51 (1H, m), 7.65 (1H, t, J 8.2 Hz), 8.15-8.18 (2H, m), 8.32-8.38 (1H, m), 9.64 (1H, s); m/z (ES+) 354.
