These common heterocyclic compound, 4592-94-3, name is 3-(4-Bromophenyl)-3-oxopropanenitrile, 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. SDS of cas: 4592-94-3
General procedure: To a stirred solution of 3-oxo-3-aryl-propionitriles 2 and Et3N (0.101 g, 1 mmol) inCH3OH:H2O (2:1, 6 mL) was added adducts of ninhydrin and malononitrile 9 (0.208 g, 1 mmol)at room temperature. After completion of the reaction [about 30-120 min, TLC (n-hexan/EtOAc,2:1) monitoring], the solvent was evaporated under vacuum and the crude product wascrystallized from CH2Cl2/n-hexan.
The synthetic route of 3-(4-Bromophenyl)-3-oxopropanenitrile has been constantly updated, and we look forward to future research findings.
