Procedure

A solution of 300 mg of ethyl (RS)-(2-allyloxy-3,5-dichloro-phenyl)-(4-carbamimidoyl-phenylamino)-acetate hydrochloride (1:1) (see Example 293.3) in 5 ml of ethanol was treated with hydrogen in ther presence of a catalytic amount of platinum dioxide for 45 minutes while stirring. The reaction mixture was suction filtered over Speedex. The filtrate was concentrated and gave 270 mg of ethyl (RS)-(4-carbamimidoyl-phenylamino)-(3,5-dichloro-2-hydroxy-phenyl)-acetate hydrochloride (1:1); MS (ISP) m/z 382/384 (M+H)+.
