2.5 g of 5-methoxy-2,4-diaminophenol and 25 mL of concentrated HCl is placed in a 45 mL Hastalloy C autoclave. The mixture is then heated to 140° C. for 16 hours at a pressure of about 200 psi. The reaction mixture is then cooled to 25° C., the reactor is vented and the product, a white solid, is filtered and dried to yield 1.2 g of crude 4,6-diaminoresorcinol dihydrochloride.
