실험 절차

To a solution of potassium cyanide (12.2 g, 0.187 mol) and sodium carbonate (36 g, 0.338 mol) in water (250 ml) was added 5-methyl furfural (7.5 ml, 75 mmol) in 1,4-dioxane (12 ml) followed by glyoxal busulphite (3.0 g, 0.289 mol) and water (240 ml). After stirring for 21/2 hr at room temperature, the reaction was worked up by adding 5N HCl(aq) to the reaction mixture carefully (HCN↑) until the pH fell to ≈1-2. Stirring was continued for 1 hr after which time, no more gas was evolved.
