Versuchsvorschrift

A solution of 1.5 g of N-(2-naphthylsulfonyl)-D-tryptophan in 30 ml of DMF is treated with 1.5 ml of ethylmorpholine. After the addition of 0.7 g of rac-3-aminomethyl-1-amidinopiperidine sulphite (Example 1)and 1.7 g of benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate the reaction mixture is stirred for 15 hours. The solvent is evaporated and the residue is taken up in 50 ml of water and extracted with 100 ml of ethyl acetate. The ethyl acetate phase is washed with water, dried and evaporated. The crude material is purified on a RP-18 column with water/acetonitrile (0-30%). There is obtained 0.8 g of (R)-N-[(RS)-1-amidino-3-piperidinylmethyl]-α(2-naphthylsulfonamido)indole-3-propionamide bisulfite, FAB-MS: 533 (M+H)+.
