실험 절차

0.600 g (2.26 mmol) of the above prepared 2-methyl-6-(3-trifluoromethyl-phenyl)-pyridine-3-carbaldehyde (example 3A]) was dissolved in 11.3 ml of abs. THF and treated at −78° C. with 1.2 ml of 2M propyl magnesium chloride solution (in EtOEt, 1.06 eq.). After stirring for 15 Min. at 0° C., the reaction mixture was carefully poured onto crashed ice/NH4Cl, extracted twice with AcOEt, washed with water, dried over sodium sulfate, and evaporated to dryness. Flash chromatography (SiO2, hexane/AcOEt=8/2) yielded then 0.281 g of the title compound as white crystals of mp. 83–85° C.
