Procedure

4-(3-Chloropropyl)-8-fluoro-4H-benzo[1,4]oxazin-3-one (95MF51(2085)) (0.25 g, 1.04 mmol), K2CO3 (0.29 g, 2.1 mmol), NaI (0.31 g, 2.1 mmol) and 4-butylpiperidine (0.15 g, 1.1 mmol) were mixed according to GP13. CC (SiO2; CH2Cl2/MeOH 10:0.2-4) gave the title compound (95MF59) (0.29 g, 80%). 1H NMR (CDCl3) δ 6.92-6.84 (m, 2H), 6.79-6.74 (m, 1H), 4.59 (s, 2H), 3.93 (t, J=7.4 Hz, 2H), 2.81 (d, J=10.8 Hz, 2H), 2.31 (t, J=7.0 Hz, 2H), 1.87-1.75 (m, 4H), 1.62 (d, J=9.2 Hz, 2H), 1.27-1.12 (m, 9H), 0.84 (t, J=6.8 Hz, 3H); 13C NMR (CDCl3) δ 163.7, 151.8 (d, J=246.0 Hz), 133.8 (d, J=14.6 Hz), 130.7 (d, J=3.5 Hz), 122.1 (d, J=8.0 Hz), 111.2 (d, J=18.4 Hz), 110.4 (d, J=3.4 Hz), 67.6, 55.8, 54.2, 40.0, 36.4, 35.8, 32.6, 29.0, 24.8, 22.9, 14.1.
