Reaction Steps

7-Chloro-4-(3-chloropropyl)-4H-benzo[1,4]oxazin-3-one (81MF2271b) (1.953 g, 7.49 mmol), K2CO3 (2.07 g, 14.9 mmol), NaI (2.24 g, 14.9 mmol) and 4-butylpiperidine (1.11 g, 7.86 mmol) were mixed according to GP11. CC (SiO2; Heptane/EtOAc 10:1-4) gave the title compound (81MF2271x) (2.46 g, 90%). 1H NMR (CDCl3) δ 7.08-6-96 (m, 3H), 4.57 (s, 2H), 3.95 (t, J=7.2 Hz, 2H), 2.85 (d, J=10.8 Hz, 2H), 2.35 (t, J=7.2 Hz, 2H), 1.93-1.78 (m, 4H), 1.66 (d, J=9.2 Hz, 2H), 1.31-1.18 (m, 9H), 0.88 (t, J=6.4 Hz, 3H); 13C NMR (CDCl3) δ 163.7, 146.0, 128.7, 127.7, 122.7, 117.6, 116.1, 67.7, 55.9, 54.3, 39.9, 36.5, 36.0, 32.7, 29.2, 24.8, 23.1, 14.2.
