A solution of 2-(2-((2-((6-methoxypyridin-3-yl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethynyl)phenyl)propanamide A69 (0.198 g, 0.449 mmol) in EtOAc (20 mL) and MeOH (10 mL) was stirred over 10% Pd/C (wetted with ca. 53% water, 0.150 g) under an atmosphere of hydrogen for 16 hours. The mixture was filtered through Celite and the solvent was removed in vacuo. Purification by column chromatography (Biotage Isolera, 40 g SiO2, 0-80% EtOAc in petroleum benzine 40-60° C.) gave the title compound 61 as a white solid (0.126 g, 63%). LCMS-D: rt 3.43 min; m/z 446 [M+H]+.
