Reaction Steps

As shown in step 6-ix of Scheme 6, to a mixture 5-bromo-N-((cis)-4-((7-morpholinoquinoxalin-5-yl)oxy)cyclohexyl)pyrimidin-2-amine (75 mg, 0.155 mmol), cesium carbonate (101 mg, 0.309 mmol), allylpalladium(II) chloride dimer (0.28 mg, 0.0015 mmol), RockPhos (2.17 mg, 0.0046 mmol) and MeOH (9.9 mg, 12.5 μL, 0.31 mmol) in toluene (2 mL) was flushed with nitrogen gas and heated to 100° C. for 18 hours. The reaction mixture was diluted with EtOAc, filtered though a layer of diatomaceous earth, and concentrated under reduced pressure. Purification by medium pressure silica gel chromatography (0-8% MeOH/DCM gradient) yielded 5-methoxy-N-((cis)-4-((7-morpholinoquinoxalin-5-yl)oxy)cyclohexyl)pyrimidin-2-amine (compound 134, 43 mg): 1H-NMR (300 MHz, CDCl3) δ 8.70 (d, J=1.9 Hz, 1H), 8.63 (d, J=1.9 Hz, 1H), 8.07 (s, 2H), 6.96 (d, J=2.5 Hz, 1H), 6.92 (d, J=2.5 Hz, 1H), 5.01 (d, J=8.1 Hz, 1H), 4.80 (q, J=5.6, 4.2 Hz, 1H), 4.03-3.87 (m, 5H), 3.80 (s, 3H), 3.42-3.27 (m, 4H), 2.29-2.10 (m, 2H), 1.99-1.82 (m, 6H).
