실험 절차

The mixture of 1.1 g of 1-methyl-β-oxo-α-ethoxycarbonyl-2-pyrrolpropionitrile, 1.1 g of aniline and 60 ml of xylene, is refluxed for 41/2 hours. After standing and cooling to room temperature overnight, the solution is filtered, evaporated and the residue recrystallized from methanol, to yield the 1-methyl-β-oxo-α-phenylcarbamoyl-2-pyrrolpropionitrile melting at 173°-174°; it is identical with that obtained according to Example 1.
