Procedure

Benzyl(5-methyl-2-pyridyl)dithiocarbamate (3 g.) was suspended in ethanol (30 ml.). Methylamine (33% ethanolic solution, 10 ml.) was added and the mixture stirred at room temperature for 1 hour. On the addition of water, the thiourea separated and was collected by filtration, dried and recrystallised from ethanol-petrol ether. Yield 2.5 g., m.pt. 161° C.
