A common compound: 5744-56-9, name is 1,3-Dimethyl-1H-pyrazole-5-carboxylic acid, belongs to pyrazoles-derivatives compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 5744-56-9<\/a><\/p>\n

Scheme I 1,3-Dimethyl-4-nitro-pyrazole-5-carboxylic acid One-hundred twelve g concentrated sulfuric acid is added to 42 ml 90% nitric acid at 70-80 C., 39 g of 1,3-dimethylpyrazole-5-carboxylic acid is added in portions over one hour such that the temperature does not go over 90 C. After 2.5 hours the reaction mixture is cooled and poured over ice. The resulting percipitate was filtered, dried, and recrystallized in ethanol, mp 141-142 C.<\/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, 5744-56-9, other downstream synthetic routes, hurry up and to see.<\/p>\n","protected":false},"excerpt":{"rendered":"
