Reaction Steps

A degassed mixture of 6-benzyl-4-chloro-1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (0.150 g, 0.483 mmol, Example 228, Step 7), tert-butyl (trans-4-aminocyclohexyl)carbamate (0.41 g, 1.9 mmol, Combi-Blocks), NaOtBu (0.14 g, 1.4 mmol, Aldrich), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (70. mg, 0.12 mmol, Aldrich) and tris(dibenzylideneacetone)dipalladium(0) (53 mg, 0.058 mmol, Aldrich) in toluene (7.5 mL) was heated at 120° C. for 2 hours. After cooling to room temperature, the reaction mixture was diluted with EtOAc and washed with water, followed by brine. The organic layer was dried over sodium sulfate, filtered and concentrated. The residue was dissolved in 1,4-dioxane (4.0 mL) and treated with 4.0 M HCl in dioxane (1.0 mL, 4.0 mmol). After stirring for one hour, solvent was removed in vacuo, and the product was purified via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (31 mg, 16%).
