Versuchsvorschrift

To 42 g. of 1-methyl-2-phenyl-3-tosyloxymethyl-pyrrolidin-5-one in 72.5 ml. of dimethylsulfoxide was slowly added 5.7 g of sodium cyanide at 45° C. The reaction was stirred for 3 hours at 100° C. and then set at ambient temperature for 18 hours. After decanting into 1500 ml. of ice water, the product was extracted with 2:1 chloroform-ether, dried (Na2SO4) filtered, and concentrated in vacuo to provide 19.0 g. of light yellow crystals.
