実験手順

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; 100 mg, 0.33 mmol), 4-amino-N-(1-ethyl-4-piperidyl)-2,5-difluoro-benzamide (Intermediate 235; 102 mg, 0.36 mmol) and caesium carbonate (213 mg, 0.65 mmol) added to dioxane (5 mL) and the suspension bubbled with nitrogen for 10 minutes. tris-dibenzylideneacetonedipalladium (II) (18 mg, 0.02 mmol) and XANTPHOS (17 mg, 0.03 mmol) were added and the mixture heated at 110° C. overnight. The mixture was filtered, and the filtrate loaded onto to an SCX-3 cartridge (10 g) pre-wet with methanol, then washed with methanol and eluted with ammonia in methanol. Product containing fractions were combined and evaporated and the resultant material purified by base modified reverse phase preparative HPLC to yield the title compound as a light orange gum (99 mg, 55%).
