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 (25.0 mg, 0.0804 mmol, Example 228, Step 7), ethanolamine (44 mg, 0.72 mmol, Aldrich), Cs2CO3 (79 mg, 0.24 mmol, Aldrich) and tBuBrettPhos Pd G3 (8.2 mg, 0.0096 mmol, Aldrich) in NMP (1 mL) and Water (38 μL) was heated at 100° C. overnight. Upon cooling, the reaction mixture was diluted with MeCN, filtered and purified via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (5.9 mg, 22%).
