Participants

Reaction Steps

A mixture of 1-(2-(R)-acetylamino-3-biphenyl-4y1-propionyl)-pyrrolidin-2-(S)-carboxylic acid (0.120 g), 6-aminomethyl-isoquinolin-1-ylamine (0.058 g), N-methyl morpholine (0.11 mL) and 0.100 g of 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) in 4.5 mL of dry N,N-dimethyl formamide was stirred for 3 h at ambient temperature. The mixture was concentrated and the remaining residue was purified by silica chromatography (dichloro-methane/methanol 8/2) to give 0.120 g (70%) of the title compound as a light yellow solid. (+)- APCI-MS: 536 (MH+).
