Related Products of 28466-26-4<\/a>, These common heterocyclic compound, 28466-26-4, name is 4-Aminopyrazole, its 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

As shown in step 5-i of Scheme 5, methyl 4-bromo-2-(bromomethyl)benzoate (Compound 2018, 2.08 g, 6.75 mmol; prepared by reacting l-(4-bromo-2- methylphenyl)ethanone with NBS),lH-pyrazol-4-amine (561 mg, 6.75 mmol), and DIEA (873 mg, 1.18 mL, 6.75 mmol) were combined in DMF (7.78 mL) and heated at 110 C for 90 min. The reaction mixture was diluted with MeOH (60 mL) and the resulting white crystaline solid was collected by filtration and dried under vacuum to give 5-bromo-2-(lH- pyrazol-4-yl)isoindolin-l-one (Compound 2019, 1.21 g, 4.35 mmol, 64% yield): ESMS (Mu+Eta) 279.99<\/p>\n
