3-Chloro-8,8-dimethyl-1-morpholin-4-yl-5,8-dihydro-6H-7-oxa-9-thia-2,4-diaza-fluorene (10 mg, 0.03 mmol) was dissolved in acetonitrile (2 mL, 40 mmol) and added 1 M sodium carbonate in water (2 mL, 2 mmol), 5-(4,4,5,5-tetramethyl-1,3-dioxolan-2-yl)pyrimidin-2-amine (9.0 mg, 0.041 mmol), and Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (1.1 mg, 0.001 6 mmol). The reaction was placed on the Biotage microwave at 120° C. for 15 minutes. The aqueous layer was pipetted off and the organic layer was concentrated in vacuo and was purified by silica gel chromatography (0 to 100% ethyl acetate/heptanes) on the CombiFlash® Rf system using a basic alumina column and concentrated in vacuo to give (85% pure) 168 (2.7 mg, 20% yield). M+1: 399.3. 1H NMR (400 MHz, CDCl3) δ 9.30 (s, 2H), 5.34 (brs, 2H), 4.08 (t, 2H), 4.01 (m, 4H), 3.87 (m, 4H), 2.95 (t, 2H), 1.62 (s, 6H)
