Versuchsvorschrift

20 g (88.6 mmol) of 4-chloro-3-nitrophenyl cyclopropyl ketone is added to a solution of 65 m of 32% HBr/acetic acid in 300 ml acetic acid and heated to 80° C. for 5 hr. The reaction mixture is cooled to room temperature and poured nto 1 L of 10% potassium carbonate solution, dried over MgSO4 filtered and treated with charcoal. The solvent is removed in vacuo, and the residue is crystallized from ether to provide the title compound.
