실험 절차

To a solution of tert-butyl 4-((3-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)carbamoyl)-5-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-4-methylphenyl)ethynyl)piperidine-1-carboxylate (250 mg, 0.413 mmol) in DCM (3 mL) was added 4M HCl in 1,4-dioxane (3 mL, 12.0 mmol) at 20° C. The mixture was stirred at 20° C. for 1 h. LCMS indicated that the reaction was completed. The reaction mixture was directly concentrated and the residue was dissolved in DCM and then neutralized with sat. NaHCO3/brine. The organic layer was dried (Na2SO4) and filtered. And the filtrate was concentrated. The residue was used for alkylation without further purification (209 mg, 100%). 1H-NMR (500 MHz, CD3OD) δ ppm 7.21 (brs, 1H), 7.07 (brs, 1H), 6.11 (s, 1H), 4.46 (s, 2H), 3.95-3.89 (m, 2H), 3.39-3.34 (m, 2H), 3.08 (q, J=7.0 Hz, 2H), 3.06-2.98 (m, 3H), 2.79-2.72 (m, 1H), 2.72-2.65 (m, 2H), 2.38 (s, 3H), 2.28 (s, 3H), 2.25 (s, 3H), 1.94-1.88 (m, 2H), 1.73-1.68 (m, 2H), 1.68-1.56 (m, 4H), 0.85 (t, J=7.0 Hz, 3H); MS (ESI) [M+H]+505.5.
