Versuchsvorschrift
To 21.4 gm. of 1-benzyl-4-hydroxymethyl-5-(3methoxyphenyl)pyrrolidin-2-one in 40 ml. of potassium dried pyridine was slowly added at -4° to -7°, 14.4 gm of p-toluenesulfonyl chloride. The reaction mixture was stirred for 3 hours at 15° and then diluted with 180 ml. of 10% hydrochloric acid. The gum was extracted with chloroform, dried (Na2SO4), filtered and concentrated in vacuo to provide 24.6 gm. of the desired product as an oil.
