2-Chlorobenzimidazole Chemical Properties,Usage,Production

Chemical Properties

BEIGE TO BROWN CRYSTALLINE POWDER

Uses

2-Chlorobenzimidazole is mainly used for the synthesis of medicine and as an intermediate in organic synthesis.

Application

2-Chlorobenzimidazole can be used to synthesize the following:
1-methyl-2-chlorobenzimidazole via reaction with dimethyl sulfate
1-ethyl-2-chlorobenzimidazole via reaction with diethyl sulfate
1-benzyl-2-chlorobenzimidazole via reaction with benzyl chloride
2-chloro-4,5,6,7-tetrabromobenzimidazole via bromination with bromine
It may be used as a building block to synthesize 4-amino-6-benzimidazole-pyrimidines.

General Description

2-Chlorobenzimidazole can be synthesized by reacting benzimidazole-2-one with phosphoryl chloride in the presence of phenol.
