PROCEDURE

实验过程

1,3-Di-(4-nitrophenyl)urea (1.8 g, 0.006 mole), diethyl malonate (1 ml, 0.006 mole), and sodium hydroxide (0.24 g, 0.006 mole) were refluxed in ethanol (100 ml) for three hours. 1,3-Di-(4-nitrophenyl)-2,4,6-(1H,3H,5H)-pyrimidinetrione precipitated as a yellow powder, m.p. greater than 250° C.
