Reaction Steps

A suspension of 10% Pd/C (0.050 g) and tert-butyl 4-(4-((4-((2-(2-methoxy-2-oxoethyl)-5-(trifluoromethyl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)piperidine-1-carboxylate (A60) (0.200 g, 0.302 mmol) in DMF (10 mL) and Et3N (1 mL) was stirred at room temperature for 16 hours under an atmosphere of hydrogen. The resulting mixture was filtered through Celite, washing with MeOH. The volatiles were removed under reduced pressure then the residue was adsorbed onto silica gel and purified by column chromatography (Biotage Isolera, SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C.; repeated twice) to give the title compound A61 (170 mg, 84%); 1H NMR (400 MHz, CDCl3) δ 8.54 (s, 1H), 7.55 (d, J=8.6 Hz, 2H), 7.49 (s, 1H), 7.47-7.45 (m, 1H), 7.41 (s, 1H), 7.37 (d, J=8.0 Hz, 1H), 7.20 (d, J=8.5 Hz, 2H), 4.37-4.17 (m, 2H), 3.79 (s, 2H), 3.69 (s, 3H), 3.24-3.14 (m, 2H), 3.21-3.06 (m, 2H), 2.92-2.72 (m, 2H), 2.71-2.52 (m, 1H), 1.90-1.74 (m, 2H), 1.68-1.60 (m, 2H), 1.48 (s, 9H). LCMS-A: rt 7.149 min; m/z 667 [M+H]+.
