Reaction Steps
10.0 g of isopropyl 2-pyrrolidone-5-carboxylate was dissolved in 58.4 g of toluene, and 13.04 g of lauroyl chloride was added thereto. Further, 6.03 g of triethylamine was dropwise added, and reacted under reflux for 2 hours. Toluene was concentrated under reduced pressure, then the reaction mixture was purified through silica gel column chromatography (hexane/ethyl acetate=5/1 to 3/1) to obtain 3.69 g of isopropyl N-lauroyl-2-pyrrolidone-5-carboxylate.
