Prepared as in Example 1 by reacting 8.0 g (0.053 m) of 2-oximino-1,4-dithiane, 15.2 g (0.058 m) of N-methyl-N-(2,4-dimethyl-3-oxo-2-pentanesulfenyl)carbamoyl chloride and 5.42 g (0.053 m) of triethylamine in 100 ml of dioxane. The product crystallized from isopropyl ether-ethyl acetate to yield 4.3 g of a white solid, (m.p. 80°-82° C.) Recrystallization raised the melting point to 85°-86° C.
