Reaction Steps

6-Chloro-N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1-(1-methylethyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.25 g, 0.669 mmol) was suspended in ethanol (4 mL) followed by addition of allylamine (0.753 mL, 10.03 mmol). The sealed contents were heated (heat block) at 140° C. for ca. 60 h, and then allowed to cool to room temperature. The reaction mixture was diluted with water (100 mL) and then filtered. The collected solid was washed with additional water and then dried in vacuum oven at 45° C. for 18 h. The final product was isolated as an off-white solid, 0.225 g (83%). LCMS E-S (M+H)=394.2. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.42 (d, J=6.82 Hz, 6H), 2.12 (s, 3H), 2.21 (s, 3H), 4.00 (t, J=5.43 Hz, 2H), 4.32 (d, J=5.05 Hz, 2H), 4.94 (quin, J=6.69 Hz, 1H), 5.09 (dd, J=10.36, 1.77 Hz, 1H), 5.18-5.29 (m, 1H), 5.85-6.01 (m, 2H), 6.68 (s, 1H), 7.37 (t, J=5.56 Hz, 1H), 7.84 (s, 1H), 8.45 (t, J=5.05 Hz, 1H), 11.55 (br. s., 1H).
