Adding a certain compound to certain chemical reactions, such as: 1314987-79-5, name is tert-Butyl 3-(4-nitro-1H-pyrazol-1-yl)azetidine-1-carboxylate, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1314987-79-5, COA of Formula: C11H16N4O4
B) tert-butyl 3-(4-amino-1H-pyrazol-1-yl)azetidine-1-carboxylate To a solution of tert-butyl 3-(4-nitro-1H-pyrazol-1-yl)azetidine-1-carboxylate (5.3 g) obtained in Step B of Example 131 in ethanol (30 mL) was added 5% palladium-carbon (4.2 g), and the mixture was stirred at room temperature for 2 hr under hydrogen atmosphere (at normal pressures). The palladium-carbon was removed by filtration through Celite, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate) to give the title compound (2.1 g). 1H NMR(300 MHz, DMSO-d6)delta1.39 (9H, s), 3.89 (2H, s), 3.98-4.08 (2H, m), 4.14-4.26 (2H, m), 4.92-5.06 (1H, m), 7.03 (1H, s), 7.13 (1H, d, J = 0.8 Hz).
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, tert-Butyl 3-(4-nitro-1H-pyrazol-1-yl)azetidine-1-carboxylate, other downstream synthetic routes, hurry up and to see.
