実験手順
Dissolve in 100 ml of ethanol 0.045 mol (10 g) of N-benzoylvaline obtained in the preceding Step, add 5 ml of concentrated sulphuric acid, then heat at reflux for 24 hours. Evaporate to dryness, take up in ether, wash with water then with a 10% potassium bicarbonate solution, dry, filter and evaporate to dryness. Ethyl N-benzoylvalinate is obtained.
