Procedure
A mixture of 3-cyano-1-methyl-2-methylisothiourea (0.65 g) and 5-aminomethyl-2-chloropyridine (0.72 g) was stirred under heating at 100° C. for three hours. Then, the reaction product was cooled to room temperature and then purified on silica gel column chromatography (eluent: ethanol/chloroform) to obtain the desired 3-(2-chloro-5-pyridylmethyl)-1-methyl-2-cyanoguanidine (0.5 g) having a melting point in the range of from 193° to 197° C.
