실험 절차

N-((4,6-Dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-6-(1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (1 equiv.) was dissolved in DMSO, to it Et3N (3 equiv.) and piperidine-3-carboxylic acid (2 equiv.) was added to it. The reaction mixture was stirred at room temperature for 15 min before PYBOP (1.5 equiv.) was added to it and stirring was continued overnight. After completion of the reaction, water was added to it. Extraction was carried out using DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4; filtered and concentrated under reduced pressure to afford crude material which was purified by column chromatography to give the desired compound (85% yield). LCMS: 532.35 (M+1)+; HPLC: 99.84% (@ 254 nm) (Rt; 5.059); 1H NMR (DMSO-d6, 400 MHz) δ 11.55 (bs, 1H), 8.83 (t, 1H), 8.44 (bs, 2H), 8.30 (s, 1H), 7.86 (s, 1H), 6.92 (bs, 1H), 5.89 (s, 1H), 5.21-5.18 (m, 1H), 4.38 (d, 2H, J=4.4 Hz), 4.31 (bs, 1H), 4.23 (bs, 1H), 3.74 (m, 2H), 3.14 (m, 4H), 2.97 (m, 1H), 2.82 (m, 1H), 2.70 (m, 1H), 2.20 (s, 3H), 2.12 (s, 3H), 1.89 (m, 1H), 1.74 (m, 2H), 1.60 (m, 1H), 1.51 (d, 6H, J=6.4 Hz).
