Reaction Steps

Added to 30 ml of methanol were 2.6 g (8.07 mmol, Referential Example 48) of 2-(4-benzylpiperazino)-5-oxo-5,6,7,8-tetrahydroquinazoline and 0.67 g (9.64 mmol) of hydroxylamine hydrochloride. The resultant mixture was heated with stirring at 60° C. for 2 hours. The reaction mixture was cooled to 20° C. and the resultant precipitate was collected by filtration, thereby obtaining 2.85 g of white solid (yield: 95%).
