Abstract
It is shown that selective replacement of the sulfur atom in the 3 position by a nitrogen atom, which leads to 2,6-dimethyl-4-amino-3H-2,6-dihydro-1,3,5-thiadiazine, occurs when 2H,6H-2,6-dimethyl-4-amino-1,3,5-dithiazine is treated with ammonium hydroxide. Under the same conditions, amines cause profound destruction of 2H,6H-2,6-dimethyl-4-amino-1,3,5-dithiazine with the production of thiourea.
