Procedure

2.16 g of phenyltrimethylammonium tribromide was added to a mixture comprising 1.14 g of 2-naphthyl isopropyl ketone and 25 ml of tetrahydrofuran, and the mixture was reacted at room temperature for 3 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure to obtain 1.59 g of oily α-bromoisopropyl 2-naphthyl ketone.
