反応手順
4-(3-Chloropropyl)-4H-benzo[1,4]oxazin-3-one (81MF08) (0.030 g, 0.13 mmol), K2CO3 (0.037 g, 0.26 mmol), NaI (0.040 g, 0.27 mmol) and 3-butylidene-8-azabicyclo[3.2.1]octane (0.029 g, 0.17 mmol) were mixed according to GP12. Prep TLC (SiO2; CH2Cl2/MeOH 10:1) gave the title compound (81MF24) (0.019 g, 41%). 1H NMR (CDCl3) δ7.22-7.19 (m, 1H), 7.05-6.96 (m, 3H), 5.24 (t, J=7.2 Hz, 1H), 5.08 (s, 2H), 4.06 (t, J=6.4 Hz, 2H), 2.61 (t, J=6.8 Hz, 2H), 2.30 (s, 2H), 2.03-1.83 (M, 7H), 1.58-1.43 (m, 2H), 1.39-1.22 (m, 3 H), 0.89 (m, 3 H); 13C NMR (CDCl3) δ164.5, 145.5, 128.7, 127.9, 124.0, 123.0, 117.1, 115.5, 67.8, 60.4, 60.2, 48.8, 41.0, 39.6, 33.7, 29.5, 26.8, 26.4, 25.8, 23.2, 13.9.
