HCID 145374274-(1H-Imidazol-1-yl)benzoyl chloride

Procedure

A suspension of 4-(imidazol-1-yl)benzoic acid (0.90 g) in thionyl chloride (2.0 ml) was heated on a steam bath under argon for one hour. Evaporation of the volatile material under reduced pressure afforded a residue which crystallized upon the addition of hexane to yield the 4-(imidazol-1-yl)benzoyl chloride as the hydrochloride salt (1.17 g), m.p. 242-247° C.
