Reaction Steps

3-[(5-Bromo-2-chloro-pyrimidin-4-yl)-methyl-amino]-N-methyl-propanamide (Intermediate 15; 2.09 g, 6.20 mmol), tris(dibenzylideneacetone)dipalladium(0) (171 mg, 0.19 mmol), (5-diphenylphosphanyl-9,9-dimethyl-xanthen-4-yl)-diphenyl-phosphane (288 mg, 0.50 mmol) and Cs2CO3 (2930 mg, 8.99 mmol) in 1,4-dioxane (50 mL) were heated at reflux for 16 h under an atmosphere of nitrogen. The reaction mixture was evaporated then suspended in DCM (20 mL) and filtered through a layer of celite washing with DCM (40 mL). Purification by column chromatography (SiO2, eluent gradient: 2-10% MeOH in DCM) afforded the title compound (190 mg, 19%) as a foam.
