Versuchsvorschrift

A solution of dimethylamine (2.0 M solution in THF, 17.2 mL, 34.5 mmol) was added to 5-bromo-2-chloro-4-methoxypyrimidine (1.540 g, 6.89 mmol) at RT. The reaction was heated to 45° C. for 30 min, then cooled and concentrated. The residue was washed and filtered with diethyl ether to give 1.57 g of 5-bromo-4-methoxy-N,N-dimethylpyrimidin-2-amine as a light yellow solid. ES+=232.0 (M+H)
