반응 단계
Under exclusion of air, 29 g (122 mmol) 4-(4-pyridylmethyl)-1(2H)-phthalazinone [for preparation, see German Auslegeschrift no. 1061788 (published Jul. 23, 1959)] in 450 ml acetonitrile is mixed with 61 ml HCl/dioxane 4N and 28 ml (306 mmol) phosphoryl chloride and stirred for 27 h at 50° C. To the white suspension, 119 g NaHCO3 in 1.45 l water is then added dropwise under ice cooling, and the mixture is stirred and the title compound filtered off.
