Procedure

The title compound was prepared in a manner similar to PREPARATION x35 using 4-(5-bromo-2-chloropyrimidin-4-yl)-N-(6-chloro-2,3-dihydro-1H-inden-1-yl)morpholine-3-carboxamide (PREPARATION x40, 567 mg, 1.201 mmol), Xantphos (52.1 mg, 0.090 mmol), palladium(II) acetate (13.48 mg, 0.060 mmol) and potassium phosphate (255 mg, 1.201 mmol) in dioxane (5 mL) and tert-butanol (1 mL). 1H NMR (400 MHz, DMSO-d6) δ 2.21-2.48 (m, 3 H), 2.87-3.05 (m, 2 H), 3.05-3.21 (m, 1 H), 3.47-3.65 (m, 2 H), 3.88-4.01 (m, 1 H), 4.08-4.32 (m, 2 H), 4.39-4.56 (m, 1 H), 7.16-7.42 (m, 4 H). ESI-MS m/z [M+H]+ calc'd for C18H16Cl2N4O2, 391.07; found 391.3.
