Electric Literature of 1260243-04-6<\/a>,Some common heterocyclic compound, 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, molecular formula is C6H9N3O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

5-amino-1H-pyrazole-4-carboxylic acid ester (1.0 g, 6.45 mmol) was dissolved in methanol (200 mL) and the solution purged with nitrogen. Formaldehyde (37% by weight, 4.5 mL, 21.18 mmol) was added followed by 10% Pd\/C (1.0 g). The reaction mixture was shaked on a Parr hydrogenator at 10 psi for 18hrs. The reaction mixture was filtered through celite to remove the catalyst and the residue washed with methanol (200 mL) and water (20 mL). The combined filtrates were evaporated in vacuo. The crude residue was triturated with methanol\/diethyl ether and the filtrate concentrated to afford a colourless oil identified as the title compound (1.1 g, 6.00 mmol, 93% yield). [MH]+= 183.7<\/p>\n
