Adding a certain compound to certain chemical reactions, such as: 285984-25-0, name is 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-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 285984-25-0, category: pyrazoles-derivatives
Example 127; {[3-(tert-butyl)-l-(4-methylphenyl)pyrazol-5-yl]amino}-N-[(2-{[5-bromo-2-methyl- l-(methylethyl)-6-oxohydropyridin-4-yloxy]methyl}-5- fluorophenyl)methyl]carboxamide; [0337] To a solution of 6-{ [2-(aminomethyl)-4-fluorophenyl]methoxy}-5-bromo- 2-methyl-3-(methylethyl)-3-hydropyrimidin-4-one (0.384g, 1.0 mmol) in dichloromethane (15 mL) and saturated solution Of NaHCO3 (15 mL), phosgene (20% in toluene, 1.042 mL, 1.97mmol) was added. The mixture was stirred for 15 min, the organic layer was dried over Na2SO4 and concentrated in vacuo, and the residue was treated with a solution of 3-(tert-butyl)-l-(4-methylphenyl)pyrazole-5-ylamine (0.229g) in dichloromethane (10 mL). The resulting mixture was stirred for 17 h at room temperature. After removal of the volatiles in vacuo the residue was purified by flash chromatography using dichloromethane/hexanes/acetone (5:5:1) as elution to give the title compound (0.366g, 57.2%) as a white solid: mp 133-135 0C; 1H NMR (CD3OD/400MHz) delta 7.44 (m, 1H),7.28 (m,lH), 6.97 (m, IH), 6.29 (s, IH), 5.44 (s, 2H), 4.60 (br.lH), 4.45 (s,2H), 2.57 (s, 3H), 2.37 (s, 3H), 1.54 (d, 6H, J = 6.8 Hz), 1.30 (s, 9H); Anal. Calcd for C31H36BrFN6O3: C, 58.22; H, 5.67; N, 13.14. Found: C, 57.72; H, 5.24; N, 12.76. ES-MS m/z 641.39 & 639.39
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine, and friends who are interested can also refer to it.
