Benzoyl chloride → 2-Pyrrolidinone, 1-benzoyl-2-(1-methylbutoxy)-, (+-)-

Participants

Reaction Steps

12.4 cm3 of a 1.5M solution of butyllithium in hexane is added at -70° C. to a solution of 3.2 g of 5-(2-pentyloxy) pyrrolidin-2-one in 130 cm3 of tetrahydrofuran. The mixture is maintained at this temperature for 20 minutes, then a solution of 2.62 g of benzoyl chloride in 20 cm3 of tetrahydrofuran is added. The solution is returned to ambient temperature, concentrated and chromatographed on silica (eluent: hexane-ethyl acetate 7-3). 3.35 g of expected product is obtained.
