Procedure

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. After filtration, the solvent is removed in vacuo and the product triterated with diethyl ether, filtered and dried.
