Reaction Steps

4-Bromo-7-bromomethyl-2-isopropyl-2H-phthalazin-1-one (0.2 g, 0.56 mmol) was dissolved in THF (1 ml), to this was added N-methyl piperazine (0.14 g, 1.4 mmol) as a solution in THF (1 ml) and the reaction mixture was stirred for 1 hour. Whereupon LC-MS indicated complete consumption of starting material, the solvent was removed under vacuum and the residue was purified by flash column chromatography (elution: 90% EtOAC, 10% MeOH) to give the title compound (0.17 g, 84% yield) as a light yellow solid.
