실험 절차
A mixture of 285 mg. of 2-amino-1-(5-amino-1H-imidazol-4-yl)ethanone dihydrochloride (Example 1), 200 ml. of absolute ethanol and 10 ml. of triethyl orthoformate is stirred and heated at reflux for 1 hour, then cooled and evaporated at reduced pressure. The residue of 6,7-dihydroimidazo[4,5-d][1,3]diazepin-8(3H)-one monohydrochloride, which crystallizes on standing, is collected by filtration, washed with ethanol, then with ether, and dried at reduced pressure; m.p. above 250° C. dec.
