Versuchsvorschrift

4.85 Grams (0.018 moles) N-(4-anilinophenyl)-2-hydroxyisobutyramide from Example 3 was dissolved in 43.6 grams concentrated sulfuric acid at room temperature in a large test tube. The test tube was then placed in a boiling water bath for 18 minutes before being rapidly cooled in a stream of cold water. This reaction solution was then added dropwise to 800 milliliters of stirred cold water over a 45 minute period. The light green product was filtered off, washed with water and dried in the air to give 3.66 grams N-(4-anilinophenyl)methacrylamide (81% yield). Analysis showed a purity of 92.1%.
