Versuchsvorschrift

2-(2-Chloropyrimidine-4-yl)-6-(2-fluoroethoxy)benzothiophene (105b, 80 mg, 0.26 mmol) obtained in Preparation Example 20 was dissolved in anhydrous tetrahydrofuran (4 mL). A 2.0 M methylamine methanol solution (NH2Me in MeOH, 0.26 mL, 0.52 mmol) was added to the reaction mixture and stirred at room temperature for 3 days. To the reaction mixture was added water and organic compounds were extracted with ethyl acetate and evaporated after a treatment with sodium sulfate. Column chromatography was performed to give the target compound 2-[2-(N-monomethylamino)pyrimidine-4-yl]-6-(2-fluoroethoxy)benzothiophene (1-35, 50 mg, 63%) as a yellow solid.
