Procedure
0.50 g (1.66 mol) of ethyl (3-(4-(aminoiminomethyl)phenyl)ureido)acetate in 20 ml of THF is treated with 2.7 ml of 1N NaOH and cooled to 0° C. 0.29 ml (1.99 mmol) of benzyl chloroformate is added to this mixture and it is stirred at room temperature for 2 h. The pH is kept between 9 and 10 using 1N NaOH. The mixture is then treated with 50 ml of water and extracted with ethyl acetate. After drying (MgSO4), the solvent is removed in vacuo and the residue is stirred with ether.
