実験手順
1 mmol of N-[4-(4-aminophenyl)butanoyl]thiazolidine hydrochloride prepared in Example 20 and 1 mmol of cyanamide were dissolved with 5 ml of anhydrous ethanol. The solution was stirred under heating at 70° C. for 4 hours. The reaction mixture was concentrated under reduced pressure to obtain a crystalline residue, which was recrystallized from an ethanol-ether mixed solvent to obtain 210 mg of colorless crystals of N-[4-(4-guanidinophenyl)butanoyl]thiazolidine hydrochloride (yield: 64%).
