Reaction Steps

A solution of 1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (10. mg, 0.054 mmol, from Step 5) in DMF (1.5 mL) was treated with K2CO3 (22 mg, 0.16 mmol) and a solution of benzyl bromide (6.4 μL, 0.054 mmol, Aldrich) in DMF (0.10 mL). After stirring for 2 hours, the 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) to afford product (12 mg, 81%).
