실험 절차

To a stirred, partial solution of NaCN (11.4 g, 0.232 mol) in DMSO 75 mL) was added 5-chloromethylindan (35.2 g, 0.211 mol) dropwise over 45 minutes. (The internal temperature was maintained below 65° C.). The resulting mixture was stirred at room temperature overnight. H2O (250 mL) was added and the mixture was extracted with ether. The organic phase was washed with H2O (200 mL), 6N HCl (100 mL), H2O (200 mL), saturated aqueous NaHCO3 (100 mL), and saturated aqueous NaCl, dried (MgSO4), and concentrated. The crude product was distilled under reduced pressure (0.6 mm) to give 28.1 g (85%) as a colorless oil, b.p. 131°) C.
