Procedure
A mixture of tert-Butyl 4-(5-((4-((2-(1-amino-1-oxopropan-2-yl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)pyridin-2-yl)piperidine-1-carboxylate A71 (0.139 g, 0.234 mmol) and 10% Pd/C (0.156 g) in DMF (3.0 mL) and Et3N (0.30 mL) was stirred under a hydrogen atmosphere for 112 hours. The mixture was filtered through Celite and concentrated under reduced pressure before being purified using silica gel column chromatography (Biotage Isolera, SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C., 0-20% MeOH in EtOAc) to give the title compound A72 (0.060 g, 42%). LCMS-D: rt 3.568 min; m/z 599.4 [M+H]+.
