실험 절차

To solution of (R)-tert-butyl 3-((4-(5-(2,6-difluorophenyl)-1H-indol-3-yl)-6-methoxypyrimidin-2-yl)amino)piperidine-1-carboxylate (130 mg, 0.243 mmol) in dioxane (2 mL) was added HCl in dioxane (4 M, 2 mL) and the mixture was heated at 90° C. for overnight. The reaction was quenched with aq.NaHCO3 and extracted with EtOAc. The organic layer was dried (Na2SO4), filtered and concentrated. The residue was washed with 50% EtOAc in petroleum ether to give (R)-4-(5-(2,6-difluorophenyl)-1H-indol-3-yl)-6-methoxy-N-(piperidin-3-yl)pyrimidin-2-amine (22 mg, 22%). MS (ESI, pos. ion) m/z: 436.1 (M+1); 1H-NMR (400 MHz DMSO-d6): δ ppm: 11.78 (brs, 1H) 8.66 (s, 1H), 8.25 (s, 1H), 7.54 (d, J=8.4 Hz, 1H), 7.41-7.46 (m, 1H), 7.21-7.22 (m, 3H), 6.70 (s, 1H), 6.48 (s, 1H), 3.80-3.83 (brs, 4H), 2.89-2.99 (m, 1H), 2.33-2.41 (m, 2H), 1.98-1.99 (m, 2H), 1.43-1.50 (m, 2H), 1.12-1.24 (m, 2H).
