Improved process for the preparation of|N-cyano-S-[1 -(pyridin-3-yl)ethyl]-S-methylsulfilimines

摘要

Cyano-substituted sulfilimines are produced efficiently and in high yield from the corresponding sulfides, cyanamide and hypochlorite by adding the sulfide to a solution of the cyanamide and hypochlorite in the presence of a nitrile solvent while maintaining the pH from about 8 to about 12.
