Procedure

A mixture of 1-[(R)-methoxycarbonylamino-cyclohexyl-acetyl]-pyrrolidine-2-(S)-carboxylic acid (0.410 g), 6-aminomethyl-isoquinolin-1-ylamine (0.227 g), N-methyl morpholine (0.58 mL) and 0.423 g of 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) in 10 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 BPLC (RP-18; H2OCH3OH 95/5→0/100) to give 0.350 g (58%) of the title compound as a white solid. (+)-APCI-MS: 468 (MH+).
