Reaction Steps

Tert-butyl 4-(4-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl) carbamoyl)-1-isopropyl-1H-pyrazolo[3,4-b]pyridin-6-yl)piperidine-1-carboxylate (0.2 g, 0.383 mmol) was taken in DCM (3 mL), to it TFA (0.6 mL) was added at 0° C. and stirred at room temperature for 3 h. On completion of reaction, DCM was removed under reduced pressure, saturated NaHCO3 solution was added to it and extraction was carried out using DCM. The combined organic layers were washed with water, 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 (60% yield). LCMS: 423.25 (M+1)+; HPLC: 99.121% (@ 254 nm) (Rt; 4.628); 1H NMR (DMSO-d6, 400 MHz) δ 8.75 (t, J=4.8 Hz, 1H); 8.26 (s, 1H); 7.49 (s, 1H); 5.89 (s, 1H); 5.22-5.16 (m, 1H); 4.36 (d, J=4.8 Hz, 2H); 3.04 (d, J=12.0 Hz, 2H); 2.84-2.92 (m, 1H); 2.60 (t, J=, 8.4 Hz, 2H); 2.20 (s, 3H); 2.10 (s, 3H); 1.65-1.81 (m, 4H); 1.49 (d, J=6.8 Hz, 6H).
