Procedure
To a 10 mL reaction vial containing stir bar were added 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 (0.060 g, 0.160 mmol), ethanol (1.5 mL), and then morpholine (0.280 mL, 3.21 mmol) via syringe at once. The contents were capped, placed into a heat block, and heated at 120° C. for 18 h and then at 135° C. for 2 hr. After cooling to room temperature, the reaction mixture was diluted with water (40 mL), adjusted to pH 6-7, and stirred for 15 min. The contents were filtered and washed with water. The product was dried in vacuum oven at 50° C. for 5 hr. The product was obtained as 57 mg (79%).
