実験手順
N-cyano-N'-[2-((3-methoxy-2-pyridyl)methylthio)ethyl]S-methylisothiourea (1.9 g) in ethanol (10 ml) was treated with ethanolic methylamine (20 ml of 33% solution) and the resultant clear solution was allowed to stand overnight. Excess of methylamine was removed by bubbling nitrogen through the solution and the crystalline precipitate was recrystallised from ethanol to yield the title product (1.2 g), m.p. 122°-123°.
