반응 단계
In a round bottomed flask, 30.04 g of vanillin (0.197 mol) and 26.0 g of sodium acetate (0.317 mol) were dissolved in 200 mL of acetic anhydride (2.12 mol). About 1 mL of pyridine was added to the flask and the mixture was heated to reflux. After 24 h, the brown solution was poured over about 500 g of crushed ice and the solution was stirred until the appearance of a yellow-brown solid. The flask was left overnight in the freezer and a dark yellow solid was obtained by filtration. The crude solid was recrystallized from acetic acid/water to give 32.3 g of a yellow beige solid in a 69% yield.
