Procedure:
H2S was passed for 45 minutes through a suspension of 2.0 g of methyl 4-[2-(p-cyanobenzamido)ethyl]phenoxyacetate in 24 ml of pyridine/triethylamine (7:1) at 0° C. The solution resulting after 12 hours was concentrated, and a suspension was made of the residue in methanol and filtered. The residue on the filter was immediately suspended in 30 ml of acetone, and 4 ml of methyl iodide were added. After 2.5 hours the precipitate was filtered off, washed with a little is acetone and, after drying, dissolved in 20 ml of methanol. 2.0 g of ammonium acetate were added and the mixture was then left to react at room temperature for 2 hours, during which a colorless precipitate formed, and this was filtered off and reprecipitated from methanol. Methyl p-[2-(p-amidinobenzamido)ethyl]phenoxyacetate was obtained as the acetate salt, melting point above 200° C., after drying under high vacuum.

Furthermore, the solution was heated at 90° C. for 10 min., from which toluene was evaporated under reduced pressure, then 3.6 ml of mixed solution of acetic acid and water (2:1) was added thereto. The resulting mixture was heated at 90° C. for 10 min. and poured into ice-water, which was subjected to extraction with dichloromethane. The obtained organic layer was washed with water and saturated brine, dried over magnesium sulfate, and evaporated. The obtained residue was separated by using silica gel chromatography (chloroform:acetone=20:1), whereby 377 mg of the objective compound was obtained, which was recrystallized from ethanol-ether in 53% yield. The physical constants are described on Table 1.
