Synthetic Route of 5744-56-9<\/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. 5744-56-9, name is 1,3-Dimethyl-1H-pyrazole-5-carboxylic acid belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.<\/p>\n

Example 14; Preparation of (S)-4-(5-chloro-1,3-dimethyl-1H-pyrazolo[4,3-d]pyrimidin-7-yl)-3-ethylmorpholine (n-1) Step 1: Preparation of 1,3-dimethyl-4-nitro-1H-pyrazole-5-carboxylic acid (n-2) To fuming nitric acid (1.26 mL, 29.97 mmol, 2.0 eq.) at 0 C. was slowly added fuming sulfuric acid (9.76 mL, 104.90 mmol, 7.0 eq.) dropwise over 30 minutes. 1,3-Dimethyl-1H-pyrazole-5-carboxylic acid (2.10 g, 14.98 mmol) was then added portion wise, maintaining the internal temperature below 60 C. The reaction mixture was stirred at 60 C. under N2 for 4 h and then cooled to room temperature (RT). The reaction mixture was poured onto ice. Once ice melted the reaction mixture was extracted with EtOAc (3\u00a1\u00c1500 mL). The organic layers were combined and washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo to give the desired compound as a white solid (2.67 g, 96.1%). 1H NMR (DMSO-d6, 500 MHz) delta ppm 3.87 (s, 3H), 2.39 (s, 3H); TLC (15% MeOH\/DCM): Rf=0.12.<\/p>\n

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,3-Dimethyl-1H-pyrazole-5-carboxylic acid, other downstream synthetic routes, hurry up and to see.<\/p>\n","protected":false},"excerpt":{"rendered":"
