To a solution of 6-(3-fluorobenzyl)-1-methyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine-7-carboxylic acid (0.050 g, 0.15 mmol, from Step 3) in DMF (3 mL) was added N,N-diisopropylethylamine (0.25 mL, 1.4 mmol, Aldrich) followed by N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.18 g, 0.49 mmol, Aldrich). After the reaction was stirred for 30 seconds, 2.0 M Methylamine in THF (0.62 mL, 1.2 mmol, Aldrich) was added. After 1 hour, the reaction was diluted with MeCN and purified via preparative HPLC-MS (C18 eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (35 mg, 67%).
