実験手順
2.2 Grams of 3-chloromethyl-6-methoxycarbostyril was dissolved in 20 ml of acetic anhydride, then 12 g of potassium acetate was added thereto and stirred at 60°-70° C. for 3 hours. The reaction mixture was poured in an ice-water and the crystals precipitated were collected by filtration. Recrystallized from acetone to obtain 2 g of 3-acetoxymethyl-6-methoxycarbostyril in the form of colorless prism-like crystals.
