A mixture of 2-naphthaleneacetonitrile (30.00 g, 0.179 mole), dicyclohexyl-18-crown-6 [1.60 g, 0.0043 mole (2.4 mole %)], 2-bromobutane (50.20 g, 0.366 mole), benzene (80 ml) and sodium hydroxide solution (50%, 80 ml) is stirred at room temperature for 16 hours. The organic layer is diluted with ether (250 ml), separated, washed successively with water, dilute hydrochloric acid and water and dried over sodium sulfate. Evaporation and distillation under vacuum gives α-sec-butyl-2-naphthaleneacetonitrile (34.3 g, 86%); b.p. 130° C. (0.1 mm).
