실험 절차

The solution of 0.3 g of 5-(1-methyl-2-pyrrolyl)-4-phenylcarbamoylisoxazole, 10 ml of 5% aqueous sodium hydroxide and the minimum amount of ethanol, is warmed on the steam cone for 5 minutes. It is filtered, acidified with 5 N hydrochloric acid and the crystals formed collected. They are washed with water and triturated with methanol to give the 1-methyl-β-oxo-α-phenylcarbamoyl-2-pyrrolpropionitrile melting at 170°-172°; it is identical with that prepared as described previously, i.e. Examples 1, 6, 9 or 10.
