Procedure:
To a stirred ice bath cooled solution of diethylbenzene (1.7 mL, 10 mmol) in methylene chloride (30 mL) under nitrogen was added aluminum chloride (2.93 g, 22 mmol). A slight exotherm resulted. To the resulting reaction mixture was added benzoyl chloride (1.2 mL, 10 mmol). The reaction mixture was allowed to warm to room temperature and was then stirred at room temperature for 1.5 hours.

A solution of 4-bromo-2-chlorobenzoic acid (2.00 g, 8.5 mmol), N-hydroxysuccinimide (1.07 g, 9.3 mmol) and EDCl (1.79 g, 9.3 mmol) in tetrahydrofuran/N,N-dimethylformamide (3:1; 40 mL) was stirred at room temperature for 18 h. The reaction was concentrated and water (50 mL) was added. The mixture was extracted with ethyl acetate (3×50 mL) and the combined organic layers were washed with brine, dried (Na2SO4), concentrated, and dried in vacuo to give 1-[(4-bromo-2-chlorobenzoyl)oxy]-2,5-pyrrolidinedione (2.59 g, 92%) as an off-white solid which was used directly in the next step without further purification.

Procedure:
To a reaction flask was added 26.1 grams (0.1 mole) of tetrachloropicolinic acid, 200 milliliters of water, 3.6 grams of 95 percent hydrazine (0.11 mole) and 10.6 grams (0.1 mole) of sodium carbonate. The mixture was heated with stirring and maintained under reflux conditions for about 1 hour. The reaction mixture was cooled to 25° C and 25 milliliters of 5 normal hydrochloric acid was added. The solid which precipitated was recovered by filtration, and washed successively with water, ethanol, benzene and hexane and air dried. The 3,5,6-trichloro-4-hydrazinopicolinic acid product was recovered in a yield of 25.6 grams (93 percent of theoretical) having a melting point of 165°-170° C. After recrystallization from a 50:50 dimethylformamide-water mixture the product (as the mono-hydrate) was found by analysis to have carbon, hydrogen and nitrogen contents of 26.6, 2.1 and 15.3 percent, respectively, as compared with the theoretical contents of 26.2, 2.2 and 15.3 percent, respectively, calculated for the above named compound.
