Vorschrift

To a suspension of 6-benzyl-4-chloro-1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (20.0 mg, 0.0644 mmol, from Example 228, Step 7), 2-propanamine (51 μL, 0.60 mmol, Aldrich) and tBuXPhos Pd G1 (7.1 mg, 0.0096 mmol, Aldrich) in tetrahydrofuran (0.3 mL) was added 1.0 M LHMDS in THF (0.19 mL, 0.19 mmol, Aldrich). The reaction was stirred for 3 days, after which time additional amounts of tBuXPhos Pd G1 (6 mg, 0.008 mmol), 2-propanamine (51 uL, 0.60 mmol), THF (0.3 mL) and 1.0 M LHMDS in THF (0.2 mL, 0.2 mmol) were added and the mixture was heated at 100° C. for 2.5 hours. After cooling to room temperature, MeOH was added, and the mixture was filtered. The product was purified by preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (0.2 mg, 1%).
