Triethylamine → HCID 20467443, compound

Participants

Reaction Steps

15.4 g of 2-ethyl-4-methyl-imidazole are dissolved in 100 ml of tetrahydrofuran; 14.6 g of triethylamine are added, and there can then added dropwise, within 30 minutes at reflux temperature, 30.8 g of 2-chloro-6-nitrobenzoyl chloride, dissolved in 50 ml of tetrahydrofuran, in the process of which triethylamine hydrochloride precipitates. After 3 hours of refluxing, the mixture is filtered with suction, and the solvent is removed in the rotary evaporator. Recrystallisation of the residue from 85 ml of toluene yields 27.7 g (67.3% of theory) of the desired product, m.p. 119°-120° C.
