实验过程
1,3-dipropyl-8-(2-amino-4-chlorophenyl)xanthine was synthesized by a modification of the method of Pfleiderer and Kempter (Ang. Int. Ed. 6:259-260, 1967). 2-nitro-4-chlorobenzoic acid (0.02 mol) was dissolved in 30 ml of methanol. 1,3-dipropyl-5-nitroso-6-aminouracil (0.01 mol) was added with stirring, followed by 0.2 mol diisopropylcarbodiimide (DICD).
