Procedure
S-Methyl N-(5-bromo-3-pyridyl)-N'-cyanoisothiourea (650 mg) and 2-phenylthioethylamine (740 mg) in pyridine (0.5 ml) were heated to 50° C. for 5 hours. To the resulting clear solution was added ether (10 ml), and the desired pure compound was collected by filtration and washed with ether.
