Reference of 660845-30-7<\/a>, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 660845-30-7, name is 5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carbaldehyde belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.<\/p>\n

In a 500 mL round-bottom flask, 6.0 g (31 mmol) of 5-chloro-3-(difluoromethyl)-1 -methyl-1 H- pyrazole-4-carbaldehyde were taken up in 30 mL of toluene. A solution of 2.4 g (62 mmol) of sodium hydroxide in 6 mL of water was added to the reaction mixture, followed by 103 mL of a 30% strength solution of hydrogen peroxide in water. During the addition, the temperature was kept below 37 C. The reaction mixture was then stirred at 50 C for 7 h. After cooling, the organic phase was extracted with 100 mL of water. The aqueous phase was acidified to pH 2 using dilute hydrochloric acid. The white precipitate formed was filtered off, washed twice with 20 mL of water and dried. This gave 3.2 g of 5-chloro-3-(difluoromethyl)-1 -methyl-1 H-pyrazole-4-carboxylic acid as a white solid. H NMR (400 MHz, DMSO-c\/6) delta ppm : 3.78 (s, 3H); 7.12 (t, 1 H, JHF = 53.60 Hz); 13.19 (s, 1 H); IR (KBr): 1688 cm”1 (C=0); 2200-3200 cm”1 broad;<\/p>\n
