Procedure

10-chloro-2-cyclopentyl-4,4-dimethyl-2,6,9,11-tetrazabicyclo[5.4.0]undeca-8,10,12-trien-5-one (Intermediate 127; 100 mg, 0.32 mmol), 4-amino-N-(1-ethyl-4-piperidyl)-2,5-difluoro-benzamide (Intermediate 235; 101 mg, 0.36 mmol) and caesium carbonate (22 mg, 0.65 mmol) added to dioxane (5 mL) and the suspension bubbled with nitrogen for 10 minutes. tris(dibenzylideneacetone) palladium (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 an SCX (10 g) cartridge pre-wet with methanol, washed with methanol and eluted with methanolic ammonia. 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 white crystalline solid (97 mg, 54%).
