Reaction Steps

A suspension of 5-amino-1-methyl-6-nitroquinazolin-2,4-dione (400 mg, 1.64 mmol) in MeOH (70 mL) was hydrogenated over 10% Pd/C (150 mg) in a Parr shaker at 50 psi until uptake ceased. The catalyst was removed by filtration and the filtrate concentrated to yield 5,6-diamino-1-methylquinazolin-2,4-dione (350 mg, 99% crude).
