Chemical Properties

beige to dark yellow powder

Uses

2-(Chloromethyl)benzimidazole is used as intermediate in pharmaceutical , in organic synthesis .

Synthesis

79-11-8

95-54-5

4857-04-9

GENERAL METHOD: A mixture of o-phenylenediamine (0.1 mol) and chloroacetic acid (0.15 mol) in 100 mL of 5N HCl was heated to reflux and stirred continuously for 3-5 hours. Upon completion of the reaction, the mixture was cooled to room temperature and subsequently neutralized with sodium bicarbonate solution. The precipitate of 2-chloromethylbenzimidazole formed was collected by filtration, washed several times with water and finally dried to obtain the pure product.
