실험 절차

A solution of N-(6-amino-7-nitro-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl)-methanesulfonamide (470 mg, 1.49 mmol) and 2,5-dimethoxytetrahydrofuran-3-aldehyde (796 mg, 4.47 mmol) in acetic acid (0.5 ml) is refluxed for five hours. The solvent is removed by rotavapor evaporation to give a brown oil which is dissolved in ethyl acetate and washed three times with water. The organic layer is dried over magnesium sulfate, filtered and the solvent removed by rotavapor evaporation to give the title compound nearly pure as a brown solid, m.p. 230-245° C. (decomp).
