Reaction Steps

4-Hydroxy-2-(4-iodophenyl)-2H-phthalazin-1-one (see Method Q) (0.30 g, 0.8 mmol), sodium 2-methyl-propane-2-thiolate (0.094 g, 0.8 mmol), CuI (0.011 g, 0.06 mmol) and ethylene glycol (0.10 g, 1.6 mmol) were dissolved in N-methyl-pyrrolidinone (NMP) (0.5 ml) under argon and heated to 150° C. Stirring at this temperature was continued for 4 d before the mixture was allowed to warm to room temperature. H2O (50 ml) was added and the precipitated solid was collected by filtration. The title compound was obtained after purification of the raw product by chromatography over silica gel with dichloromethane (0.21 g, 78%). 1H-NMR: (400 MHz, D6-DMSO) 12.35 (1H, s), 8.73 (1H, d), 8.33–8.41 (3H, m), 8.14 (2H, d), 8.01 (2H, d), 1.70 (9H, s); MS (ESI+)=327.14 (M+H)+.
