Reaction Steps

To a suspension of 6-benzyl-1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridin-4-amine (32.0 mg, 0.110 mmol, from Step 3) in tetrahydrofuran (1 mL) was added acetyl chloride (15.1 μL, 0.213 mmol, Aldrich) and N,N-diisopropylethylamine (76 μL, 0.44 mmol). After 3.5 hours, the product was purified by preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (19 mg, 52%).
