실험 절차

2 Grams of 3-acetoxymethylcarbostyril was dissolved in 30 ml of methanol containing 0.6 g of sodium hydroxide, then the mixture was refluxed for 3 hours. After removal of methanol by distillation, to the residue thus obtained was added water and the crystals precipitated were collected by filtration. Recrystallized from acetone to obtain 1.3 g of 3-hydroxymethyl-6-methoxycarbostyril in the form of light yellowish needle-like crystals.
