Reaction Steps

Dissolved in 30 ml of ethanol and 10 ml of acetic acid was 0.64 g (2 mmol, Referential Example 47) of 2-(4-benzylpiperazino)-5-oxo-5,6,7,8-tetrahydroquinazoline, followed by an addition of 64 mg of 10% Pd-C. The quinazoline derivative was hydrogenated at 50° C. for 1 hour under atmospheric pressure. After cooling the reaction mixture to room temperature, the catalyst was filtered off and the solvent was distilled off from the filtrate under reduced pressure. The residue was recrystallized from ethyl acetate to obtain 0.42 g of the intended product as light yellowish crystals (yield: 90%).
