PROCEDURE

实验过程

To 100 g (0.65 mol) of 6-amino-1-ethyl-2,4-(1H,3H)-pyrimidinedione (II), dissolved in 1 liter hot water, was added 145 ml of 5 N HCl and 50 g of NaNO2 (0.72 mol) which was dissolved in water. After cooling the red crystals were filtered off and washed with water. Yield 97.7 g (83%) (III) NMR.
