In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 285984-25-0, name is 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. category: pyrazoles-derivatives<\/a><\/p>\n

To a stirred solution of CDI (223 mg, 1.38 mmol) in dry DCM (3.5 mL) was added Intermediate A1 (315 mg, 1.38 mmol) as a solid, portion-wise, over 12 min and the resulting solution maintained at RT for 4 hr. An aliquot of this solution (2.0 mL, 0.79 mmol) was added to a solution of Intermediate G1, (140 mg, 0.39 mmol) in dry THF (5.0 mL), and the reaction mixture was kept at RT for 17 hr and was then partitioned between saturated aq. NaHCO3 (30 mL) and DCM (30 mL). The aq. layer was extracted with DCM (30 mL) and the combined organic extracts were dried and evaporated in vacuo. The residue was purified by flash column chromatography (SiO2, 12 g, [5% MeOH in EtOAc] in isohexane, 0-45%, gradient elution) to afford the title compound, Example 14, as an off white solid (127 mg, 52%); Rt 5.40 min (Method 1 basic); m\/z 611\/613 (M+H)+ (ES+); 1H NMR (400 MHz, DMSO-d6) delta: 1.26 (9H, s), 2.37 (3H, s), 3.37 (3H, s), 4.07 (2H, s), 5.31 (2H, s), 6.34 (1H, s), 7.18-7.23 (2H, overlapping m), 7.31-7.34 (2H, overlapping m), 7.38-7.40 (2H, overlapping m), 7.85 (1H, d), 8.21 (1H, br s), 8.33 (1H, dd), 8.60 (1H, br s), 8.95 (1H, br s), 10.01 (1H, br s).<\/p>\n

The synthetic route of 285984-25-0 has been constantly updated, and we look forward to future research findings.<\/p>\n
