Sodium hydride (13 mg, 0.32 mmol, 60% in mineral oil) was added to a solution of 1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (20 mg, 0.1 mmol, from Example 2, Step 5) in DMF (3.0 mL). After stirring for 10 minutes, a solution of 4-(bromomethyl)pyridine hydrobromide (0.027 g, 0.11 mmol, Aldrich) in DMF (0.8 mL) was added. The mixture was stirred for 45 minutes and then quenched by the addition of water, diluted to 5 mL with MeCN, filtered and purified by preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH) (1.0 mg, 3%).
