Versuchsvorschrift
A mixture of 5-bromo-2-chloro-4-methoxypyrimidine (3 g, 13.4 mmol) and dimethylamine (2 M in THF, 33.6 mL, 67.1 mmol) in THF (20 mL) was stirred for 18 h at rt and concentrated. The residue was purified by flash chromatography (hexane/EtOAc, 9:1) to afford 2.95 g of the title compound. tR: 1.04 min (LC-MS 2); ESI-MS: 232.0/234.0 [M+H]+ (LC-MS 2); Rf: 0.34 (hexane/EtOAc 9:1).
