Versuchsvorschrift

Sodium ethoxide (40 gms) was stirred in 1 L of dimethyl sulfoxide until solution was complete. Then, 100 g of ethyl acetamido-cyanoacetate was added, and again stirred until solution was complete. 2-Bromoindane (101 g) was slowly added, using a few ml of DMSO to wash the container and addition funnel. The solution was stirred over a weekend.
