Reaction Steps

The title compound was prepared in the same manner as described in example 109 using 1-(1-methylethyl)-6-(3-thienyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (70 mg, 0.244 mmol), DMSO(2 mL), 3-(aminomethyl)-4,6-dimethyl-2(1H)-pyridinone (68.9 mg, 0.365 mmol) HCl salt, N-methylmorpholine (0.107 mL, 0.974 mmol), 1-hydroxy-7-azabenzotriazole (33.2 mg, 0.244 mmol) and EDC (93 mg, 0.487 mmol). The final product was collected as 75 mg (73%).
