Potassium Iodide → HCID 178475874, compound

Participants

Reaction Steps

To a solution of 3.0 g. (8.4 mmol.) of 2-benzoyl-3-bromomethylquinoxaline 1,4-dioxide and 0.90 g. (9.2 mmol.) of potassium acetate in 40 ml. of N,N-dimethylformamide, was added 0.22 g. (1.3 mmol.) of finely ground potassium iodide. The reaction mixture was stirred for 1.5 hours at ambient temperature, and then it was poured into 1,000 ml. of ether. The solid which precipitated was removed by filtration and discarded. Evaporation of the filtrate in vacuo left a yellow solid which was washed with methanol and dried, to give 2.7 g. (94% yield) of 2-benzoyl-3-acetoxymethylquinoxaline 1,4-dioxide, m.p. 164°-167° C.
