Reaction Steps

To an 8 mL screw-cap vial was added N-cyclopropyl-6-iodo-quinazolin-4-amine (0.25 mmol 78 mg), (3-chlorophenyl)boronic acid, (1.2 equiv., 0.30 mmol, 47 mg), 1-4 dioxane (0.6 mL), potassium phosphate tribasic, (2M in H2O, 3 equiv., 0.75 mmol, 0.0.38 mL), and Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(11) (0.05 equiv.; 0.013 mmol, 9 mg). The reaction was capped and shaken at 60° C. for 1 h. The reaction was cooled to room temperature and the phases separated. Organic phase was then concentrated. Crude was purified by reverse phase HPLC yielding 35 mg of product. 1H NMR (400 MHz, DMSO) δ 8.60-8.49 (m, 2H), 8.44-8.35 (s, 1H), 8.18-8.05 (d, J=8.7, 1H), 7.93-7.87 (s, 1H), 7.84-7.71 (m, 2H), 7.62-7.51 (t, J=7.9 Hz, 1H), 7.51-7.43 (d, J=8.4 Hz, 1H), 3.12-2.98 (m, 1H), 0.90-0.78 (m, 2H), 0.72-0.64 (m, 2H). LCMS M/Z (M+H)=296.
