Versuchsvorschrift

1.0 g (5.4 mmol) of 3-(trifluoromethyl)phenylacetonitrile and 767 mg of iodomethane (5.4 mmol) are placed in 5 ml toluene at 80° C. and slowly treated with a 50% suspension of sodamide in toluene. Next the mixture is stirred 1 hr more at 80° C., then cooled to RT and treated with water, then dichloromethane. The organic phase is separated, washed with water, dried over magnesium sulphate and freed of solvent on the rotary evaporator. The residue (1.7 g, 84% of theory) contains the title compound with a purity of ca. 53% by GC/MS and is used without purification for the next reaction.
