実験手順

10-chloro-2-cyclohexyl-6-methyl-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-5-one (Intermediate 266; 33 mg, 0.113 mmol), 4-amino-2,5-difluoro-N-(1-methyl-4-piperidyl)benzamide (Intermediate 59; 29 mg, 0.108 mmol) and caesium carbonate were added to dioxane (3 mL) and the suspension bubbled with nitrogen for 10 minutes. tris(dibenzylideneacetone) palladium (II) (4 mg, 0.006 mmol) and XANTPHOS (6 mg, 0.1 mmol) were added and the mixture heated at 100° C. for 16 hours. The reaction mixture was cooled to room temperature and filtered. The filter-cake was washed with DCM and the filtrate evaporated. The residue was dissolved in DCM and purified on a silica column eluting with a gradient of 0-5% 2M ammonia in MeOH/DCM over 30 column volumes. Fractions containing product were combined and evaporated to a solid, which was triturated with isohexane then filtered and dried to yield the title compound as a pale yellow solid (46 mg, 81%).
