To a solution of 7-hydroxy-2-isopropyl-4-bromo-2H-phthalazin-1-one (0.8 g, 0.0028 mol) in DMF (8 ml), was added potassium carbonate (2 g, 0.014 mol). After 5 min, 2-chloroethyl methyl sulfide (0.34 g, 0.0028 mol) was added and the solution was heated to 100° C. for 24 hours. After this time LC-MS indicated the complete consumption of starting material and the mixture was cooled, concentrated under vacuum and purified by flash column chromatography (elution: 70% heptane, 30% EtOAc) to give the title compound (0.3 g, 24% yield) as a white solid.
