Versuchsvorschrift

To a solution of tert-butyl 4-(6-((3-fluoro-2′-(trifluoromethyl)-2,4′-bipyridin-5-yl)methylcarbamoyl)pyridin-3-yl)piperazine-1-carboxylate 49-5 (106 mg, 0.21 mmol) in dichloromethane (2 mL) was added TFA (1 mL) dropwise. The mixture was stirred at room temperature for 2 hours, and the solvents were removed by rotary evaporation. The residue was dissolved in ethyl acetate (100 mL), washed with saturated aqueous NaHCO3 solution, H2O and brine, dried over Na2SO4 and concentrated to dryness by rotary evaporation to give N-((3-fluoro-2′-(trifluoromethyl)-2,4′-bipyridin-5-yl)methyl)-5-(piperazin-1-yl)picolinamide 49-6 as yellow solid. MS m/z 461.2 (M+1)
