Procedure
The (RS)-(4-carbamimidoyl-phenylamino)-[5-ethoxy-2-fluoro-4-(2-hydroxy-ethoxy)-phenyl]-acetic acid ethyl ester hydrochloride (100 mg) described in example 1.6 was dissolved in DMF (1 ml). At 0° C., ethyl chloroformate (24 mg) and triethylamine (67 mg) were added. The mixture was stirred for 1 h at 0° C. The product was isolated by extraction and column chromatography (CH2Cl2/acetone) to give 106 mg of (RS)-[4-(amino-ethoxycarbonylimino-methyl)-phenylamino]-[5-ethoxy-2-fluoro-4-(2-hydroxy-ethoxy)-phenyl]-acetic acid ethyl ester as a colorless foam. MS: 492 ([M+H]+).
