Hydrogenation of 6-nitro-3H-quinazolin-4-one (2 g) in EtOH (200 mL) was catalyzed by Pd/c (10%, 200 mg) under a H2 balloon for 1 h. MeOH (200 mL) was added to the mixture. The suspension was filtered through a layer of Celite® and the filtrate was concentrated in vacuum to give the desired compound.
