실험 절차

0.600 g (2.26 mmol) of the above prepared 2-methyl-6-(3-trifluoromethyl-phenyl)-pyridine-3-carbaldehyde was dissolved in 11 ml of abs. THF and treated at −15° C. with 1.08 ml of 2.5 M ethyl magnesium chloride solution (in THF). After 30 Min., the reaction mixture was carefully poured onto crashed ice/NH4Cl, extracted twice with AcOEt, washed with water and brine, dried over sodium sulfate, and evaporated to dryness. Flash chromatography (SiO2, hexane/AcOEt=8/2) produced finally 0.473 g of pure title compound as white crystals of mp. 97-99° C.
