Imidazole → (1H-Imidazol-1-yl)(2,4,6-trimethylphenyl)methanone

Participants

Reaction Steps

136 g (2.0 moles) of imidazole in 1,000 ml of ether are initially taken, and 146 g (0.8 mole) of 2,4,6-trimethylbenzoyl chloride are added dropwise to the stirred mixture in the course of 30 minutes at from 10° to 20° C. Stirring is continued for 5 hours at room temperature, and the precipitated imidazole hydrochloride is filtered off under suction, the filtrate is evaporated down and the residue is distilled to give 116.4 g (68% of theory) of N-(2,4,6-trimethylbenzoyl)-imidazole of boiling point 128° C./0.01 mbar.
