3synthesis methods

Product Name:2-Amino-5-bromopyrimidine
CAS Number:7752-82-1
Molecular formula:C4H4BrN3
Molecular Weight:174

The synthesis of 2-Amino-5-bromopyrimidine is as follows:The 2-aminopyrimidine (2.5g, 26.29mmol) was dissolved in acetonitrile (25mL) was added N- bromosuccinimide (4.6g, 27.9mmol) under ice-cooling, stirred in the dark overnight at room temperature. Recovery of the solvent under reduced pressure, washed with water (100 mL) was washed, filtered off with suction, and dried in vacuo to give a white solid. Yield: 97%.
