実験手順
To 0.401 g (1.072 mmol) of the above prepared 2-bromomethyl-6-(4-trifluoromethyl-phenyl)-nicotinic acid methyl ester, dissolved in 4.0 ml of abs. MeOH, was added 0.116 g (2.15 mmol) of sodium methoxide and the mixture stirred for 4 h at ambient temperature, when TLC indicated the complete disappearance of starting material. Pouring onto crashed ice/NH4Cl-solution, twofold extraction with AcOEt, washing with water and brine, drying over magnesium sulfate, and evaporation of the solvents, followed by flash chromatography (SiO2, hexane/AcOEt=9/1), produced 0.279 g of pure title compound as white solid.
