Vorschrift

To NaH (0.246 g, 10.2 mmol) in 10 ml of DMF at 20° is added 4-(3-methyl-2-butenoxy)phenol (1.33 g, 10.2 mmol) in 5 ml of DMF. After anion formation is complete, the reaction is cooled to 5° C. and 2-chloropropionitrile (1.095 g, 12.2 mmol) is added gradually. Then, the reaction mixture is warmed to RT and heated at 45° for 18 hrs. The reaction is cooled to RT, poured into ice water and extracted with ether. The combined organic layers are washed with 10% NaOH, followed with water until neutral, and with brine, and dried over calcium sulfate. Ether is removed under vacuum to give 2-[4-(3-methyl-2-butenoxy)phenoxy]propionitrile.
