Adding a certain compound to certain chemical reactions, such as: 1904-31-0, name is 1-Methyl-1H-pyrazol-3-amine, 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 1904-31-0, Formula: C4H7N3<\/a><\/p>\n

(E)-(3-Chloro-4-methanesulfonyl-phenyl)-cyclopentyloxyimino-acetic acid (93 mg, 0.27 mmol), 1-methyl-1H-pyrazol-3-ylamine (29 muL, 0.30 mmol) and N,N-diisopropylethylamine (141 muL, 0.81 mmol) were combined in acetonitrile (1.25 mL) and cooled in an ice bath. O-(7-Azabenzotriazole-1-yl)-N,N,N’N’-tetramethyluronium hexafluorophosphate (103 mg, 0.27 mmol) was added and the ice bath was removed. After stirring 2 h, the reaction mixture was evaporated in vacuo. The residue was treated with saturated aqueous sodium bicarbonate solution (1 mL) and extracted with chloroform (2*3 mL). The combined organic phases were dried over sodium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (Merck silica gel 60, 40-63 mum; 60percent ethyl acetate\/hexanes) to afford (E)-2-(3-chloro-4-methanesulfonyl-phenyl)-2-cyclopentyloxyimino-N-(1-methyl-1H-pyrazol-3-yl)-acetamide (79 mg, 69percent) as a white solid after lyophilization from aqueous acetonitrile: LC-MS (ESI) m\/e calcd for C18H21ClN4O4S [M+] 424.10, found 425 [M+H+]; H1-NMR (400 MHz, CDCl3) delta ppm 1.64 (m, 4 H, 2*CH2), 1.86 (m, 4 H, 2*CH2), 3.29 (s, 3 H, SO2CH3), 3.85 (s, 3 H, NCH3), 4.88 (p, J=4.1 Hz, 1 H, OCH), 6.69 (d, J=2.3 Hz, 1 H, Ar), 7.28 (d, J=2.3 Hz, 1 H, Ar), 7.55 (dd, Jo=8.2, Jm=1.3 Hz, 1 H, Ar), 7.66 (d, Jm=1.3 Hz, 1 H, Ar), 8.18 (d, Jo=8.2 Hz, 1 H, Ar), 9.16 (s, 1 H, NH).<\/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, 1-Methyl-1H-pyrazol-3-amine, other downstream synthetic routes, hurry up and to see.<\/p>\n
