Reaktionsschritte

To a solution of 4,6-dichloropyrimidine (1.0 equiv.) in EtOH (0.44 M) was added morpholine (1.0 equiv.) followed by triethylamine (1.10 equiv.). The resulting mixture was stirred at RT for 16 hours. The reaction mixture was then concentrated in vacuo and dried under high vacuum over 20 h to yield 4-(6-chloropyrimidin-4-yl)morpholine as a white solid in 93% yield. LCMS (m/z) (M+H)=200.0/201.8, Rt=0.35 min. 1H NMR (400 MHz, <cdcl3>) δ ppm 3.53-3.71 (m, 4H) 3.72-3.83 (m, 4H) 6.51 (s, 1H) 8.39 (s, 1H) 11.75 (br. s., 1H).
