Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 4058-91-7, name is 5-Amino-1-methyl-1H-pyrazole-4-carboxylic acid, A new synthetic method of this compound is introduced below., Quality Control of 5-Amino-1-methyl-1H-pyrazole-4-carboxylic acid<\/a><\/p>\n

56 To a solution of 5-AMINO-L-METHYL-LH-PYRAZOLE-4- carboxylic acid (7.1 g), N- (2-AMINOETHYL) tritylamine (15.1 g) and triethylamine (10.1 g) in chloroform (200 ml) was added N- (3-DIMETHYLAMINOPROPYL)-N – ethylcarbodiimide hydrochloride (9.6 g), and the mixture was stirred at room temperature for 16 hours. The reaction mixture was washed successively with 10% aqueous citric acid solution, brine and saturated aqueous sodium hydrogencarbonate solution. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was triturated with ethyl acetate and dried in vacuo to give 5-AMINO-1- METHYL-N- [2- (TRITYLAMINO) ETHYL]-LH-PYRAZOLE-4- carboxamide (11.4 g) as a solid. 1H-NMR (CDCl3) 8 2.35-2. 38 (2H, m), 3.45-3. 49 (2H, M), 3.63 (3H, s), 5.15 (1H, br), 5.91 (1H, br), 7.17-7. 49 (16H, m)<\/p>\n
