Reaction Steps

6-cyclopropyl-1-(1,1-dimethylethyl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (53 mg, 0.194 mmol), 3-(aminomethyl)-6-methyl-4-propyl-2(1H)-pyridinone (71.3 mg, 0.242 mmol), 1-hydroxy-7-azabenzotriazole (52.8 mg, 0.388 mmol), EDC (74.3 mg, 0.388 mmol) and N-methylmorpholine (0.085 mL, 0.776 mmol) were suspended in Dimethyl Sulfoxide (DMSO) (10 mL) and stirred at room temperature for 16 hours. Added 25 mL of water and stirred for 10 minutes. The contents were filtered and dried, and collected as 70 mg. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.93 (t, J=7.33 Hz, 3 H), 0.96-1.09 (m, 4 H), 1.54 (m, J=7.52, 7.52, 7.52, 7.52, 7.33 Hz, 2 H), 1.68 (s, 9 H), 2.12 (s, 2 H), 2.17-2.27 (m, 1 H), 2.33 (s, 3 H), 2.5(2 H), 4.34 (d, J=5.05 Hz, 2 H), 5.89 (s, 1H), 7.01 (s, 1 H), 8.54 (t, J=4.80 Hz, 1 H), 11.50 (s, 1 H).
