実験手順
To 22.0 gm. of 5-(3-methoxyphenyl)-1-phenyl-4-(p-toluenesulfonyloxymethyl)pyrrolidin-2-one in 150 ml. of dimethylformamide was added 21 ml. of 40% aqueous dimethylamine, the solution refluxed for 3 hours and then 21 ml. more of 40% aqueous dimethylamine added and reflux continued for an additional 3 hours. After cooling the reaction was decanted into ice water and acidified. Extraction with ether followed by basification of the aqueous phase with potassium carbonate yielded a semi-solid which was extracted with chloroform, dried (Na2SO4), filtered and concentrated in vacuo to a solid. Recrystallization from acetonitrile provided 7.0 gm. of beige crystals, m.p. 88°-92°.
