Reaction Steps

3.4 g (30 mol) of 2-chloroacetyl chloride were dissolved in anhydrous dioxane and a solution containing 3.8 g (30 mol) of 4-chloroaniline was added dropwise. After an hour, the batch was poured into ice water, acidified using dilute hydrochloric acid, the supernatant was removed by suction and the residue was washed with water until neutral. The reaction product was recrystallized from ethanol. The yield was 3.2 g.
