Reaction Steps

A microwave vial was charged with 2-chloro-7,7-dimethyl-4-morpholin-4-yl-6,7-dihydro-[1,4]dioxino[2,3-d]pyrimidine from Example 104 (50 mg, 0.18 mmol), 5-indolylboronic acid (42 mg, 0.26 mmol), Pd(PPh3)2Cl2 (12 mg, 0.02 mmol) and sodium carbonate (0.5 mL, 0.5 mmol, 1M aqueous solution) in acetonitrile (1.5 mL) then evacuated and back filled with nitrogen before being heated to 120° C. for 30 minutes using microwave irradiation. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with methanol and the product eluted with 2M ammonia in methanol. The basic fractions were combined and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC (Phenomenex Gemini 5 μm C18, 0.1% HCO2H in water on a gradient of acetonitrile 5-98%) affording 115 as a white solid (11 mg, 17%). LCMS: RT=4.37 min, [M+H]+=367. 1H NMR (400 MHz, CDCl3): δ 8.67 (1H, s), 8.28-8.20 (2H, m), 7.39 (1H, d, J=8.6 Hz), 7.23-7.19 (1H, m), 6.61 (1H, broad s), 3.91 (2H, s), 3.90-3.82 (8H, m), 1.48 (6H, s)
