Reaction Steps

A solution of tert-butyl 4-(4-((4-((2-(2-methoxy-2-oxoethyl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)-1H-pyrazol-1-yl)piperidine-1-carboxylate (A134) (392 mg, 0.671 mmol) in EtOAc (40 mL) and DMF (2 mL) was stirred with 10% Pd/C (wetted with ca. 53% water, 100 mg) under a hydrogen atmosphere at room temperature overnight. The mixture was filtered through Celite and the filter cake was washed with EtOAc (50 mL). The volatiles were removed in vacuo and the resulting yellow oil was adsorbed onto silica gel and purified by silica gel column chromatography (Biotage Isolera, 40 g SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C. then 0-20% MeOH in EtOAc) to give the title compound (A135) as a yellow solid (300 mg, 76%), 1H NMR (400 MHz, Chloroform-d) δ 8.44 (s, 1H), 7.85 (s, 1H), 7.64-7.46 (m, 1H), 7.22-7.06 (m, 4H), 4.32-4.04 (m, 3H), 3.67 (s, 2H), 3.60 (s, 3H), 3.14-2.94 (m, 4H), 2.87-2.75 (m, 2H), 2.14-1.99 (m, 2H), 1.97-1.79 (m, 2H), 1.40 (s, 9H).
