Versuchsvorschrift

8-Acetylamino-3,4-dihydrocarbostyril (11.8 g, 57.8 mols) was suspended in 90 ml of 20% hydrochloric acid and the suspension was stirred while heating under reflux for 1 hours. The reaction mixture was poured into ice water and neutralized with 5 N sodium hydroxide followed by adjusting to pH of about 8. Crystals which precipitated were collected by filtration to give 7.87 g of 8-amino-3,4-dihydrocarbostyril.
