2′-chloro-9′-cyclopentyl-5′-methyl-8′,9′-dihydrospiro[cyclopropane-1,7′-pyrimido[5,4-b][1,4]diazepin]-6′(5′H)-one (Intermediate 130; 85 mg, 0.30 mmol), 4-amino-5-chloro-2-fluoro-N-(1-methyl-4-piperidyl)benzamide (Intermediate 173; 101 mg, 0.33 mmol) and XANTPHOS (16 mg, 0.03 mmol) were dissolved in 1,4-dioxane (7.5 mL). Caesium 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, which was subsequently washed with methanol and eluted with ammonia in methanol. Product containing fractions were concentrated and purified by base modified reverse phase preparative HPLC to yield the title compound as a white solid (100 mg, 60%).
