Reaktionsschritte

To a stirred solution of 250 mg (0.77 mmol) trifluoromethanesulfonic acid 2-amino-6-furan-2-yl-5-methyl-pyrimidin-4-yl ester in 10 ml DME was added 489 mg (2.12 mmol) 2-(aminomethyl)quinoline dihydrochloride and the mixture heated at 80° C. for 16 hours. The reaction mixture was then concentrated in vacuo. Chromatography (ethyl acetate/hexane 4/1) followed by trituration in ether/hexane afforded 80 mg (50%) 4-chloro-6-furan-2-yl-5-methyl-pyrimidin-2-ylamine as a white crystalline solid. ES-MS m/e (%): 212 (M{37Cl}+H+, 50), 210 (M{35Cl}+H+, 100).
