Procedure

To 30 mg (0.16 mmol) copper(I)iodide in 2 ml THF at −30° C. are added 0.71 ml of a 3-Methyl magnesium bromid in diethyl ether. After 30 minutes at −30° C. 200 mg (0.54 mmol) {[2-methoxyphenyl][2-(trifluoromethyl)oxiranyl]methyl}naphthalene-5-amine in 0.5 ml THF are added. The reaction mixture is stirred for 2 hours while warmed to −10° C. and then poured into a saturated ammonium chloride solution. Phases are separated and the aqueous layer is extracted twice with ethyl acetate. The combined organic phases are washed with brine, died over sodium sulphate and evaporated. Flash chromatography on silica gel (ethyl acetate in hexane 10% to 50%) yields 12 mg of the title compound.
