Versuchsvorschrift

5.00 g of 1-Amino-6-aminomethyl-isoquinoline and 6.20 Boc-L-proline were dissolved in 88 mL DMF. 10.6 g of TBTU was added followed by a dropwise addition of N-methylmorpholine. Stirring was continued for 1 h at ambient temperature and the solvent was removed i.vac. The residue was extracted with 5% aqueous NaHCO3 solution and with ethyl acetate. The organic layer was separated and dried (NaSO4). The solvent was removed to give 10.7 g (quant.) of N-(1-Amino-isoquinolin-6-ylmethyl)-1-tert.butoxycarbonyl-prolinamide as an oil.
