Reaction Steps
Prepared as in Example I by reacting 2.94 g (0.0169 m) of 3,5,5-trimethyl-2-oximino-thiazolidin-4-one, 4.0 g (0.0169 m) of N-methyl-N-(2,4-dimethyl-3-oxo-2-pentanesulfenyl)carbamoyl chloride and 1.7 g (0.0169 m) of triethylamine in 200 ml of dioxane. The productcrystallized from isopropyl ether to yield 2.5 g of a white solid, m.p. 112°-114° C.
