Procedure

4-(3-Chloropropyl)-4H-benzo[1,4]thiazin-3-one (81MF07) (0.18 g, 0.74 mmol), K2CO3 (0.20 g, 14.8 mmol), NaI (0.22 g, 14.8 mmol) and 4-propoxypiperidine (0.12 g, 0.81 mmol) were mixed according to GP12. CC (SiO2; Heptane/EtOAc 4:1-4) gave the title compound (81MF07KS) (0.205 g, 79%). 1H NMR (CDCl3) δ 7.33 (d, J=7.6 Hz, 2H), 7.21 (d, J=3.2 Hz, 2H), 7.00-6.96 (m, 1H), 4.03 (t, J=7.2 Hz, 2H), 3.38-3.34 (m, 4H), 3.26-3.21 (m, 1H), 2.69 (t, J=5.6 Hz, 2H), 2.33 (t, J=7.2 Hz, 2H), 2.04 (t, J=9.8 Hz, 2H), 1.86-1.76 (m, 4H), 1.58-1.51 (m, 4H), 0.90 (t, J=7.2 Hz, 3H); 13C NMR (CDCl3) δ 165.2, 139.7, 128.5, 127.2, 124.1, 123.4, 118.1, 75.2, 69.7, 55.4, 51.5, 43.2, 31.8, 31.7, 25.3, 23.4, 10.8.
