실험 절차

Using the procedure of Example 1, 5 g of 4,5-diaminopyrimidine and 10 g of ethyl pentanimidoate hydrochloride [J.A.C.S., Vol. 64, p 1827 (1942)] using dimethylformamide as solvent were reacted to obtain 2.1 g of the desired product which after crystallization from ethyl acetate melted at 166° C. The product was crystallized from ethyl acetate to obtain 1.8 g of the expected product melting at 168° C. 200 mg of an analytical sample was obtained by an additional crystallization of 300 mg of the product from ethyl acetate melting at 168° C.
