Procedure

499 mg of ethyl (RS)-[4-(tert-butoxycarbonylamino-imino-methyl)-phenylamino]-(2-ethoxycarbonylmethoxy-phenyl)-acetate were treated in 14 ml of THF with 2 ml of 1N LiOH, adjusted to pH 4 after 4 hrs. with 2 ml of 1N HCl and evaporated in a vacuum. From acetonitrile-water there were obtained 182 mg of (RS)-(4-carbamimidoyl-phenylamino)-(2-carboxymethoxy-phenyl)-acetic acid, m.p. 223° C., MS: 344 (M+H)+.
