실험 절차

5-Methyl-6-methylamino-nicotinonitrile (example 121, 0.345 g, 2.34 mmol) was dissolved in 3.2 ml of abs. THF and treated at 0° C. with sodium hexamethyldisilazide-solution (1M in THF, 7.03 ml, 3.0 eq.) and, after 5 Min., 4 eq. of methyl iodide (0.58 ml). The mixture was allowed to react for 1 h at room temperature. Pouring onto crashed ice/NH4Cl, twofold extraction with AcOEt, washing with water, drying over sodium sulfate, and evaporation of the solvents, followed by flash chromatography (silica gel, hexane/AcOEt=7/3) yielded 0.330 g of the title compound as off-white solid.
