Versuchsvorschrift
To a solution of 4-(1-carboxyethyl)-1(2H)-phthalazinone (1.5 g, 6.9 mmol) in EtOH (50 mL) was added thionyl chloride (1.10 mL, 15.1 mmol). The mixture was stirred at 80° C. for 4 hours, cooled to 0° C., and quenched with 1M NaHCO3 (40 mL). The aq layer was extracted with EtOAc (2×50 mL), dried (Na2SO4), filtered, and concentrated to give the title compound: MS (ESI+) M/Z 247 (M+H)+.
