Procedure

A 28 g. of portion of 9-(N,N-dimethylcarbamoyl)fluorene was added to a 3-liter flask, and 1 liter of tetrahydrofuran was added. The mixture was heated to 45°, and 10 ml. of Triton B was added. The mixture was stirred at constant temperature for 15 minutes, and then 8 g. of acrylonitrile was added in one portion. The mixture was then stirred at reflux temperature for 3 hours, and was cooled and concentrated under vacuum to obtain 51.8 g. of oil. The product was isolated as described in Example 1 and was recrystallized from hexane to obtain 15 g. of first-crop purified product, m.p. 109°-110°. Infrared analysis showed a characteristic carbonyl band at 1610 cm-1, and a characteristic nitrile band at 2220 cm-1.
