Procedure

To a solution of 6-(3-chlorobenzyl)-1-methyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine-7-carboxylic acid (0.034 g, 0.10 mmol, from Step 4) in DMF (2 mL) was added N,N-diisopropylethylamine (0.16 mL, 0.93 mmol, Aldrich) followed by N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.12 g, 0.32 mmol, Aldrich) and then by 2.0 M methylamine in THF (0.40 mL, 0.80 mmol, Aldrich). After stirring for 15 minutes, the reaction mixture was diluted with MeCN and purified via preparative HPLC-MS (C18 eluting with a gradient of MeCN and H2O containing 0.15% NH4OH). Yield: (25 mg, 71%).
