実験手順
Eleven and one-tenth grams of N-allyl-N-benzyl dichloroacetamide was dissolved in 12 ml. of diglyme and 1 g. of anhydrous ferrous chloride added. The mixture was heated at reflux under nitrogen until conversion to the pyrrolidinone was complete as indicated by GLPC. The mixture was diluted with methylene chloride, washed with 5 percent hydrochloric acid, separated, dried over anhydrous magnesium sulfate, treated with activated carbon and Florisil and stripped under vacuum. Yield was 6 g. of the title compound, nD30 1.5387.
