Benzoyl chloride → 1-Benzoyl-5-(octyloxy)pyrrolidin-2-one

Participants

Reaction Steps

16.5 cm3 of a 15% solution of butyllithium in hexane is added at -60° C. to 5.3 g of 5-n-octyloxy pyrrolidin-2-one in solution in 200 cm3 of tetrahydrofuran. After agitation for 20 minutes at -60° C., then, while maintaining these conditions, a solution of 3.5 g of benzoyl chloride in 50 cm3 of tetrahydrofuran is added. Agitation is continued while allowing to return to ambient temperature. After concentration and chromatography on silica (eluent: toluene-ethyl acetate 8-2), 4.2 g of the product sought is obtained.
