Participants

Reaction Steps

To 11.4 mg (0.10 mmol) N-ethylpiperazine was added a solution of 43 mg (0.10 mmol) 1-(7-Methyl-6,7,8,9-tetrahydro-5H-1,4,7,10a-tetraaza-cyclohepta[f]inden-10-yl)-azetidine-3-carboxylic acid and 0.026 mL (0.15 mmol) DIPEA in 0.5 mL DMF at room temperature. 35.3 mg (0.11 mmol) TBTU was dissolved in 0.5 mL DMF and the solution was added to the reaction mixture. Stirring was continued for 2 h and the reaction mixture was allowed to stand for overnight. The mixture was filtered over basic alumina followed by two washing cycles with 1.5 mL DMF. The solvent was removed and the residue was purified by column chromatography to yield the desired compound.
