Procedure

Analogously to Example 145, from methyl (RS)-(4-cyano-phenylamino)-(3-ethoxy-5-hydroxy-phenyl)-acetate via methyl (RS)-(4-cyano-phenylamino)-(3-ethoxy-5-trifluoromethanesulphonyloxy-phenyl)-acetate by reaction with thiophene-2-boronic acid there was obtained the compound methyl (RS)-(4-cyano-phenylamino)-(3-ethoxy-5-thiophen-2-yl-phenyl)-acetate, which was converted into methyl (RS)-(4-carbamimidoyl-phenylamino)-(3-ethoxy-5-thiophen-2-yl-phenyl)-acetate hydrochloride.
