Reaction Steps

7-Chloro-4H-benzo[1,4]oxazin-3-one (81MF2271a) (1.74 g, 9.47 mmol), Cs2CO3 (4.63 g, 14.2 mmol) and 3-chloro-1-iodopropane (2.13 g, 10.4 mmol) were mixed according to GP6. CC (SiO2; Heptane/EtOAc 10:1-5) gave the title compound (81MF2271b) (1.95 g, 79%). 1H NMR (CDCl3) δ 7.03-6.96 (m, 3H), 4.59 (s, 2H), 4.07 (t, J=7.2 Hz, 2H), 3.61 (t, J=6.4 Hz, 2H), 2.17-2.10 (m, 2H); 13C NMR (CDCl3) δ 164.0, 146.0, 129.1, 127.3, 123.0, 117.8, 115.5, 67.7, 42.4, 39.2, 30.0.
