Procedure
Subsequently, 8.71 g (33.2 mM) of triphenylphosphine, 25 ml of carbon tetrachloride and 15 ml of THF were placed in 200 ml-three necked flask. Under stirring at room temperature, 4.55 g (16.6 mM) of the above-prepared 2-octyl-5-carbamoylindan was gradually added to the above mixture, followed by washing with 10 ml, of THF and stirring for 3 hours at 45°-50.4° C. to precipitate a crystal. After the reaction, the crystal was removed from the reaction mixture by filtration and the filtrate was evaporated under reduced pressure to obtain a residue. The residue was purified silica gel column chromatography (eluent: toluene/ethyl acetate=100/1) and recrystallized from methanol to obtain 4.24 g of 2-octyl-5-cyanoindan (Yield: 99.8%).
