A degassed mixture of 6-benzyl-4-chloro-1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (80. mg, 0.26 mmol, from Example 228, Step 7), tert-butyl 4-aminopiperidine-1-carboxylate (210 mg, 1.0 mmol, Combi-Blocks), NaOtBu (49 mg, 0.51 mmol, Aldrich), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (30. mg, 0.051 mmol, Aldrich) and tris(dibenzylideneacetone)dipalladium(0) (24 mg, 0.026 mmol, Aldrich) in toluene (4.0 mL) was heated at 100° C. overnight. After cooling, the reaction mixture was diluted with EtOAc and washed sequentially with water and brine. The organic layer was dried over sodium sulfate, filtered and concentrated. The crude product was dissolved in DCM (5.0 mL) and was treated with 4.0 M HCl in dioxane (2.0 mL, 8.0 mmol) for 1 hour. The reaction mixture was concentrated in vacuo. The product was purified via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (40 mg, 38%).
