Application of 288-88-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 288-88-0 as follows.
To a stiffing solution of 4-fluorobenzaldehyde (10.0 g, 80.6 mmol) in DMF (150 mL) were added K2CO3 (13.3 g, 96.7 mmol) and 1,2,4-triazole (6.67 g, 96.7 mmol) and the resultant reaction mixture was stirred at 120 C. for 6 h. After completion of reaction (by TLC), the reaction mixture was diluted with H2O and extracted with EtOAc (3¡Á100 mL). The combined EtOAc layer was washed with H2O and brine, dried over Na2SO4, and concentrated under reduced pressure to afford the title compound as a solid (9.0 g, 65%): mp 145-149 C.: 1H NMR (400 MHz, CDCl3) delta 10.08 (s, 1H), 8.70 (s, 1H), 8.16 (s, 1H), 8.06 (d, J=8.0 Hz, 2H), 7.92 (d, J=8.0 Hz, 2H); ESIMS m/z 173.9 ([M+H]+).
According to the analysis of related databases, 288-88-0, the application of this compound in the production field has become more and more popular.
