Procedure
5-Bromo-2-methyl-1-indanone (2.0 g) and cuprous cyanide (4.0 g) in quinoline (50 ml ) were stirred at 200° for 2 hours. The mixture was cooled, treated with chloroform (100 ml ) and filtered to remove copper salts. The filtrate was then washed with 6N hydrochloric acid (3×100 ml ) and evaporated to give the crude product as a brown gum. Crystallisation from ethanol-water gave 5-cyano-2-methyl-1-indanone (1.46 g, m.p. 90°-1°).
