Procedure

At a temperature of about 18°, powdered benzhydrazide (126 g, 1 mole) was suspended in stirred benzene (1.6 l), and 24-mesh phthalic anhydride (148 g, 1 mole) was added portionwise over 15 to 20 minutes. After the addition the reaction mixture was stirred for a further hour. The product, 1-benzoyl-2-(2-carboxybenzoyl) hydrazine (III) (R1 =H) was collected on a filter, pressed free of benzene and air dried, 276 g, 98%, M.P., 205°-208°.
