Embodiment 1
[0069] Example 1: 2',4'-difluoro-2-(1 H Preparation of -1,2,4-triazol-1-yl)acetophenone (referred to as compound 1)
[0070] Add triazole (6.9 g, 0.1 mol) and potassium carbonate (13.8 g, 0.1 mol) into a 250 mL round bottom flask, take an appropriate amount of acetonitrile as solvent, add 2',4'-difluoro-2-chlorobenzene under stirring Ethyl ketone (19.0 g, 0.1 mol). After the reaction, the solvent was evaporated to dryness, and an equal volume of water and chloroform was added to extract three times. The organic phase was washed with saturated ammonium chloride solution and distilled water, and dried over anhydrous sodium sulfate. After rotary evaporation and recrystallization, 14.5 g of light yellow solid was obtained, yield: 65%, melting point: 108-110°C (commercial product 107-111°C).
Embodiment 2
[0071] Embodiment 2: ( Z )-1-(4-fluoro-2-(piperidin-1-yl)phenyl)-3-phenyl-2-(1 H -1,2,4-triazol-1-yl) prop-2-en-1-one (compound 2 for short) and ( Z )-1-(2,4-bis(piperidin-1-yl)phenyl)-3-phenyl-2-(1 H Preparation of -1,2,4-triazol-1-yl)prop-2-en-1-one (compound 3 for short)
[0072] In a 100 mL single-necked flask, an appropriate amount of toluene was added as a solvent, and 2',4'-difluoro-2-(1 H -1,2,4-triazol-1-yl) acetophenone (2.23 g, 10 mmol), benzaldehyde (1.06 g, 10 mmol) and piperidine (1.87 g, 22 mmol), then add glacial acetic acid 3 Drop it as a catalyst, install a water separator, keep stirring at 130°C under reflux, and the reaction is complete after 6 hours. Toluene was distilled off under reduced pressure, and an equal volume of water and chloroform were added for extraction three times. The organic phase was dried over anhydrous sodium sulfate and then concentrated. Column chromatography was performed using petroleum ether and ethyl acetate (7 / 1, V / V) as elu...
Embodiment 3
[0075] Embodiment 3: ( Z )-1-(4-fluoro-2-morpholinophenyl)-3-phenyl-2-(1 H -1,2,4-triazol-1-yl) prop-2-en-1-one (referred to as compound 4) and ( Z )-1-(2,4-dimorpholinophenyl)-3-phenyl-2-(1 H Preparation of -1,2,4-triazol-1-yl)prop-2-en-1-one (Compound 5 for short)
[0076] According to the synthetic method of embodiment 2. The starting material is 2',4'-difluoro-2-(1 H -1,2,4-triazol-1-yl)acetophenone (2.23 g, 10 mmol), benzaldehyde (1.06 g, 10 mmol) and morpholine (1.91 g, 22 mmol) to obtain compound 4 (yellow solid, 2.09 g, yield: 56%, melting point: 123~124°C) and compound 5 (red syrup, 0.84 g, yield: 19%).
[0077] Compound 4: 1 H NMR (300 MHz, CDCl 3 ) δ: 8.11 (s, 1H, trizole 5-H), 8.06 (s, 1H, trizole 3-H), 7.49 ~ 6.70 (m, 9H, C=CH, PhH), 3.77 ~ 3.74 (t, 4H, J = 4.2 Hz, morpholino OCH 2 ), 3.01 ~ 2.98 (t, 4H, J = 4.5 Hz, morpholino NCH 2 ) ppm; MS (m / z): 379 [M+H] + .
[0078] Compound 5: 1 H NMR (300 MHz, CDCl 3 ) δ: 8.11 (s, 1H, trizole 5-H), 8.06 ...
