2,6-Dimethylbenzoyl chloride → HCID 21472157, compound

Participants

Reaction Steps

In 30 ml of pyridine, were dissolved 1.1 g (6.25 mmol) of 1-phenyl-imidazolidin-2,4-dione and 1.12 g (6.65 mmol) of 2,6-dimethylbenzoyl chloride to conduct a reaction at 60° C. for 3 hours. After completion of the reaction, pyridine was distilled off under reduced pressure, and the resultant residue was subjected to extraction with ethyl acetate. The organic layer was washed with dilute hydrochloric acid and with saturated saline. The thus-washed organic layer was then dried over anhydrous magnesium sulfate, and the solvent was distilled off. The resultant residue was purified by column chromatography on silica gel (developing solvent: n-hexane/ ethyl acetate) and subjected to crystallization from n-hexane/ethyl acetate to obtain 122 mg (yield: 5.8%) of the title compound.
