246 mg (0.86 mmol) of 4-(3-isopropyl-4-methoxybenzyl)-3,5-dimethylaniline (Example VII) are dissolved with 97 mg (0.96 mmol) of triethylamine in 10 ml of dichloromethane, and 160 mg (1.17 mmol) of ethoxalyl chloride are added dropwise. The mixture is stirred at room temperature for 4 hours, washed with sodium bicarbonate solution and water and dried over sodium sulphate, and the solvent is removed in vacuo. Purification by chromatography affords 128 mg (38%) of ethyl 2-[4-(3-isopropyl-4-methoxybenzyl)-3,5-dimethylanilino]-2-oxoacetate.
