To a solution of 10.0 g (0.042 m) of N-methyl-N-(2,4-dimethyl-3-oxo-2-pentanesulfenyl)carbamoyl chloride and 6.06 g (0.042 m) of 1-naphthol in 75 ml of dioxane was added 4.26 g (0.042 m) of triethylamine. After stirring at room temperature for 17 hours the reaction mixture was diluted with 500 ml of cold water and the product taken into ethyl acetate. The organic phase was washed in turn with 1.0 percent sodium hydroxide and water and then dried over magnesium sulfate. On removal of the solvent it yielded 9.4 g of a residual oil.
