Benzoyl chloride (1.635 g) is added dropwise to 4,5,6,7-tetramethyl-indan-1,2-dione 2-oxime (2.53 g) and triethylamine (2.25 g) in anhydrous dichloromethane (60 ml) at 0° C. The reaction mixture is stirred at room temperature for 1.5 hours after which the solid product is filtered off and allowed to-stir with water (150 ml), refiltered and dried. The organic filtrate is washed with 1M HCl, 10% brine, saturated sodium bicarbonate solution, 10% brine and treated with magnesium sulphate.
