2-Propanone, 1-(acetyloxy)-3-chloro- → 3-acetoxy-2-oxopropyl N-(2,3,4-trifluorophenyl)dithiocarbamate

Participants

Reaction Steps

Triethylammonium N-(2,3,4-trifluorophenyl)dithiocarbamate (2.15 g) prepared in the same manner as in Reference Example 1 was added to methylene chloride (30 ml) and thereto 1-acetoxy-3-chloroacetone (1.0 g) was added dropwise at 2° to 7° C. with stirring over a period of 10 minutes. The mixture was stirred for 20 minutes and washed with 3N hydrochloric acid and then with water. The organic layer was dried over anhydrous magnesium sulfate and then the solvent was distilled off under reduced pressure. The residue was recrystallized from a mixed solvent of hexane ethyl acetate to give the title compound (1.43 g) as colorless crystals.
