2-chloro-N-(4-chlorophenyl)-3-oxobutanamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Chloro-N-(4-chlorophenyl)-3-oxobutanamide (24.7 g, 0.1 mole), 1,2-ethanedithiol (9.4 g, 0.1 mole) and a small amount of p-toluenesulfonic acid were heated under reflux in benzene (150 ml), using a Dean-Stark trap to remove water (1.9 ml collected). The reaction mixture was filtered, treated with triethylamine (8 ml), and refluxed for a further 30 minutes. The mixture was then washed with water, dilute hydrochloric acid, and water. Evaporation of the benzene gave a white solid, which was recrystallized from absolute ethanol. The product melted at 115°-117° C. (24 g, 84% yield). to remove water (1.9 ml collected) The reaction mixture was filtered treated with triethylamine (8 ml) refluxed for a further 30 minutes The mixture was then washed with water, dilute hydrochloric acid, and water Evaporation of the benzene gave a white solid, which was recrystallized from absolute ethanol
