Generally, it requires fewer steps, and cheap raw materials. 18213-75-7, name is 5-Amino-1-methyl-1H-pyrazole-4-carboxamide, A new synthetic method of this compound is introduced below., <a href=\"https:\/\/www.ambeed.com\/products\/18213-75-7.html\">Formula: C5H8N4O<\/a><\/p>\n<p>The mixture of 5-amino-1-methyl-1H-pyrazole-4-carboxamide (70 g, 0.49 mol), EtONa (117 g, 1.72 mol) and the intermediate from Step B ( (272 g, 1.16 mol) in EtOH (1 L) was stirred in a sealed bottle at 120C overnight. The mixture was concentrated and the residue was diluted with H2O (2 L) and then adjusted to pH = 6 with 2 N aqueous HC1 solution. The mixture was extracted with EtOAc (1 L x 3). The combined organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel column chromatography using petroleum ether\/EtOAc = 1 : 1 to give the title product.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
