Procedure

2′-chloro-9′-cyclohexyl-5′-methyl-8′,9′-dihydrospiro[cyclopropane-1,7′-pyrimido[5,4-b][1,4]diazepin]-6′(5′H)-one (Intermediate 270; 103 mg, 0.32 mmol), 4-amino-5-chloro-N-(4-dimethylaminocyclohexyl)-2-fluoro-benzamide (Intermediate 175; 92 mg, 0.29 mmol), and XANTPHOS (16 mg, 0.03 mmol) were dissolved in 1,4-dioxane (7.5 mL). Caesium 10 carbonate (210 mg, 0.59 mmol) was added and the system purged with a stream of nitrogen for 15 minutes before tris(dibenzylideneacetone) palladium (II) (17 mg, 0.02 mmol) was added. The apparatus was evacuated and backfilled with nitrogen (×3) and then heated at 100° C. for 3 hours. The mixture was cooled, filtered and the filtrate absorbed on to an SCX column, and the column then washed with methanol and eluted with ammonia in methanol. Product containing fractions were combined and evaporated and the residue purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (49 mg, 28%).
