Participants

Reaction Steps

A mixture of 3-{2-[(1H-Pyrrole-2-carbonyl)-amino]-benzoylamino}-thieno[2,3-c]pyrazole-1,5-dicarboxylic acid 1-ethyl ester (198.5 mg, 0.4246 mmol), 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU, 204 mg, 0.6369 mmol), DIEA (0.29 mL, 1.6984 mmol) and cumylamine (115 mg, 0.8492 mmol) in DMF (10 mL) was stirred at room temperature. After 2 hours the mixture was diluted with AcOEt (40 mL) and washed with saturated NaHCO3, water and brine. The organic layer was dried over Na2SO4 and evaporated to give 495 mg of crude that was used in the next step without further purification, LC-MS: Rt 7.36; [M+H]+ 585.
