To a round bottom flask was added water (170 ml) and hydrazine dihydrochloride salt (41.9 gm, 398.8 mmol). To a round bottom flask was added To a round bottom flask was added water (170 ml) and hydrazine dihydrochloride salt (41.9 gm, 398.8 mmol). The solution was brought to reflux and dichloromandelic anhydride (66.6 gm, 398.9 mmol) was added portionwise. The reaction was stirred at reflux for 30 min. After this time, the solution was cooled to rt and the solid was collected by filtration to give the title compound,
