反応手順

17.3 g (125 mmol) of AlCl3 were added to a solution of 3.91 g (50 mmol) of benzene in 30 ml of analytical grade methylene chloride, while cooling with ice. 11.9 g (52 mmol) of 2-bromoisobutyryl bromide were then added, and stirring was continued at 0° C. for 1 hour and at room temperature for 2 hours. The mixture was heated under reflux for a further 15 hours and then worked up analogously to Example A. The crude product was chromatographed on 100 g of silica gel (hexane/methylene chloride 1:1). The yield was 5.1 g (70%).
