1-(4-methoxybenzyl)-4-chloro-1H-pyrazolo[3,4-b]pyridine (0.200 g, 0.731 mmol) was charged to a pressure tube in 5 mL of NMP. 2-morpholinoethanamine (0.144 ml, 1.10 mmol) was added and the reaction was heated to 150° C. for 72 hours. After cooling, the reaction mixture was diluted with 25 mL of EtOAc and washed with water (2×15 mL) and then dried with brine and Na2SO4.
