Procedure

To a solution of 5-methyl-1,3-cyclohexanedione (23) (45.4 g, 360 mmol) in acetic acid (540 mL) was added bromine (19.4 mL, 378 mmol) over 5 min. After 30 min of stirring (with mechanical stirrer), the reaction mixture was filtered. The solid was left under high vacuum overnight and used in the subsequent step without further purification.
