Vorschrift

As for Example 6, 1-methyl-2-pyrrolecarboxaldehyde is converted to α-(1-methyl-2-pyrrolyl)-4-morpholineacetonitrile. The preceding compound is reacted with ethyl acrylate and the resulting 1,4-addition product is heated at 100° C. with 6 N hydrochloric acid to give 3-(1-methyl-2-pyrrolylcarbonyl)propionic acid.
