Versuchsvorschrift
30 Grams of 8-chloroacetylcarbostyril was mixed with 300 ml of pyridine and stirred at 80°-90° C. for 2.5 hours under heating. Then the reaction mixture ice-cooled and crystals formed were collected by filtration and washed with ether. Recrystallized from methanol to obtain 40.85 g of 8-(α-pyridiniumacetyl)carbostyril chloride 1/2-hydrate.
