Reaction Steps

A mixture of N-[3-(2,6-dichlorobenzyloxy)pyrid-2-yl]-N'-(4-chlorophenyl)thiourea (2.0 g, 0.0045 mol), yellow mercuric oxide (1.18 g, 0.0054 mol) and 33% w/w methylamine in methylated spirit (40 ml) was stirred at room temperature for 24 hours. The solvent was removed in vacuo and the black residue was boiled with chloroform and filtered hot. Evaporation of the solvent and recrystallisation from acetonitrile gave the desired product.
