실험 절차

12.1 ml of dimethyl sulphate were added at room temperature while stirring well to a suspension of 20.0 g (85.0 mmol) of resorufin, 17.6 g of freshly powdered potassium carbonate and 10 drops of tris-[2-(2-methoxyethoxy)ethyl]amine in 150 ml of dioxan. The reaction mixture was subsequently stirred at 100° for 2 hours, cooled and then treated with 150 ml of water. The solid was filtered off, washed with water and dried over phosphorus pentoxide. 11.5 g (59.5%) of resorufin methyl ether of m.p. 240°-244° (dec.) were obtained.
