To a suspension of 4-(4-amino-pyridin-2-ylmethyl)-2H-phthalazin-1-one (21) (0.40 g, 1.48 mmol) in anhydrous DCM (160 mL) and triethylamine (0.46 mL, 4.09 mmol), was added a dropwise preformed solution of triphosgene (0.27 g, 0.93 mmol) in anhydrous DCM (30 mL). The reaction was stirred for 6 hrs at room temperature. The reaction mixture was then concentrated to dryness in vacuo yielding a grey solid. Single peak in LC-MS analysis, (yield taken to be quantitative) no purification performed. m/z (LC-MS, ESP), RT=3.79 mins, (M+MeOH) 329.0.
