実験手順

A suspension of 10% Pd/C (100 mg), tert-butyl 4-(4-((4-((2-(1-amino-1-oxobutan-2-yl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)piperidine-1-carboxylate (A1) (167 mg, 0.275 mmol) and Et3N (1.0 mL) in DMF (10 mL) was stirred under an atmosphere of hydrogen for 16 hours. The resulting mixture was diluted with EtOAc (60 mL), filtered through Celite then the solvent removed under reduced pressure to give the title compound A2 as a yellow oil (412 mg, 98%); 1H NMR (400 MHz, d6-DMSO) δ 10.15 (s, 1H), 8.67 (s, 1H), 7.67 (d, J=8.6 Hz, 2H), 7.49-7.42 (m, 1H), 7.31 (s, 1H), 7.22-7.14 (m, 5H), 6.87 (s, 1H), 4.06 (d, J=10.5 Hz, 2H), 3.61 (dd, J=8.8, 6.1 Hz, 1H), 3.29-2.94 (m, 4H), 2.88-2.74 (m, obscured by solvent), 2.70-2.59 (m, 1H), 2.04-1.92 (m, 1H), 1.74 (d, J=12.6 Hz, 2H), 1.61-1.43 (m, 3H), 1.41 (s, 9H), 0.83 (t, J=7.3 Hz, 3H). LCMS-A: rt 6.722 min; m/z 612 [M+H]+.
