Reaktionsschritte
A solution of 4,6-dichloro-5-pyrimidinecarbaldehyde (15.0 g, 84.8 mmol) in DMF (360 mL) was charged with potassium monopersulfate (38.9 g, 254 mmol) and stirred over night at rt. The reaction mixture was filtered through a pad of celite and partitioned between EtOAc and water and separated. The aqueous was extracted with EtOAc (3×) and the combined organic fractions were washed with water (2×), brine, and dried over sodium sulfate, filtered, and concentrated to afford the title compound. 1H NMR (DMSO-d6, 400 MHz): δ=9.02 (s, 1H).
