Reaktionsschritte
To a solution of 4,6-dichloro-pyrimidine (7.45 g, 50 mmol) in iPrOH (50 mL) was added a solution of methyl amine in THF (2M, 30 mL, 60 mmol) at room temperature. The resulting mixture was stirred for 18 hours. The mixture was concentrated and the residue was purified by flash chromatography on silica eluting with DCM:EtOAc=6:1-1:1 to obtain the title compound (4.4 g, yield: 62%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 2.96 (d, 3H), 5.22-5.36 (bs, 1H), 6.35 (s, 1H), 8.35 (s, 11H); MS (ESI): 144 [M+H]+.
