Procedure

To 100 ml of methanol, were added 2.0 g of 4-amidino-2-methoxyphenyl cinnamate methanesulfonate and 0.5 g of a 10% palladium-carbon. Hydrogen was fed to the mixture which was stirred vigorously to facilitate absorption. The reaction mixture was freed from the insolubles by filtration and from the solvent by distillation. The residue was recrystallized from ethanol to obtain 1.5 g of the same 4-amidino-2-methoxyphenyl 3-phenylpropionate methanesulfonate.
