실험 절차
60 Grams of 6-(α-chloroacetyl)carbostyril was suspended in 0.5 kg of pyridine and stirred at 80°-90° C. for 2 hours, then the suspension was stirred under ice-cooling for 1 hour. The crystals thus precipitated were collected by filtration and recrystallized from methanol to obtain 70 g of 6-(α-pyridiniumacetyl)carbostyril chloride 1/2-hydrate in the form of colorless needle-like crystals.
