Vorschrift

Under salt-ice cooling, 3-(4-bromobenzoyl)propionic acid (75.0 g, 291.7 mmol) was added to fuming nitric acid (200 mL) in portions at such a rate that the temperature of the reaction solution could be maintained at −5° C. or lower. After stirring at −12° C. to −10° C. for 1 hour, the reaction solution was poured onto ice. The solid which precipitated was collected by filtration, washed with purified water, and thereafter dried under reduced pressure to obtain 3-(4-bromo-3-nitrobenzoyl)propionic acid (91.0 g).
