(RS)-[(4-{[2-(2,6-difluoro-4-hydroxy-phenyl)-2-ethoxy-acetylamino]-methyl}-phenyl)-imino-methyl]-carbamic acid benzyl ester (100 mg) was dissolved in EtOH (2 ml). 1.25 M HCl in EtOH (0.1 ml) was added and the mixture was hydrogenated 1.5 h at 1 atm H2 in the presence of a catalytic amount of 10% Pd/C. After filtration of the catalyst the solvent was removed to obtain 71 mg (88%) of (RS)-N-(4-carbamimidoyl-benzyl)-2-(2,6-difluoro-4-hydroxy-phenyl)-2-ethoxy-acetamide hydrochloride. White powder. MS 364.3 ([M+H]+).
