Versuchsvorschrift

A mixture of 4-phenylpyrimidine (10 g, 64 mmol) and conc. H2SO4 (33 ml) was added to a mixture of conc. H2SO4 (22 ml) and conc. HNO3 (16 ml) at 0° C. The resulting mixture was stirred at 0° C. for 2 hr, poured onto crushed ice, and extracted with CH2Cl2. The extract was washed with a 5% aqueous NaHCO3 solution, dried over MgSO4 and concentrated under reduced pressure. The residue was triturated with isopropanol and the precipitate was filtered off and dried under reduced pressure to give (57) (6.4 g, 50%).
