Procedure

2-(4-Acetoxyphenyl)-imidazo[1,5,a]quinoxaline-1,3(2H,5H)-dione (250 mg) wasadded to an ethanol solution (50 mL) saturated with HCl. The solution was stirred for 2 hours and the solvent was removed in vacuo to yield 2-(4-Hydroxyphenyl)-imidazo[1,5,a]quinoxaline-1,3(2H,5H)-dione (Compound 41), m.p. 318°-322° C.
