Procedure

Powdered aluminum chloride (1.34 g, 10 mmol) was suspended in dichloromethane (10 ml). To the suspension was added dropwise acetyl chloride (1.02 ml, 14.3 mmol) over 5 minutes with stirring and under ice-cooling. Subsequently, a solution of the compound (8) (2.075 g, 7.2 mmol) prepared above in dichloromethane (6 ml) was added dropwise over 15 minutes. After being stirred for 2 hours at the same temperature and then for 2.5 hours at room temperature, the solution was poured into ice-water and extracted with dichloromethane. The organic layer was washed with water, dried over anhydrous magnesium sulfate and then the solvent was distilled off under reduced pressure. The resulting residue was recrystallized from ethyl acetate (3 ml) and hexane (3 ml) to provide 2.01 g of the title compound (9). Yield: 84.4% mp 129-130° C.
