70% | With bis-triphenylphosphine-palladium(II) chloride; potassium carbonate In 1,4-dioxane; water at 50℃; for 16h; Schlenk technique; Inert atmosphere; | 8-(Dibenzo[b,d]thiophen-4-yl)-2-morpholino-4H-1,3-benzoxazin-4-one 20k General procedure: 6-bromo,8-bromo or 6-chloro-8-bromo-2-morpholino-4H-1,3-benzoxazin-4-one 17, 18 or 19 (0.48mmol) was combined with powdered potassium carbonate (200mg, 1.44mmol), bis(triphenylphosphine)palladium(II) dichloride (3mg, 0.04mmol) and the appropriate arylboronic acid (0.52mmol) in a 25mL Schlenk flask containing 1,4-dioxane (7mL) and RO water (3mL) under nitrogen. The reaction mixture was heated at 50°C for 16h with stirring before being cooled, evaporated to dryness under reduced pressure, 10mL of RO water was added. Extracted with chloroform (3×10mL), the chloroform was dried using anhydrous magnesium sulphate and evaporated under reduced pressure. Recrystallization from an appropriate solvent yields pure 6- or 8- aryl-substituted-2-morpholino-4H-1,3-benzoxazin-4-ones compounds 20-22. 8-bromo-2-morpholino-4H-1,3-benzoxazin-4-one 17(150mg) was allowed to react with 4-dibenzothienylboronic acid (119mg) according to general procedure C. Recrystallization from 2-propanol gave 20k as an off white solid (139mg, 70% yield), mp 179-182°C. νmax (ATR)/cm-1 3060w, 2972w, 2867w (C-H), 1674m (C=O), 1626m (C=C), 1557s (C=N). 1H NMR (300MHz, DMSO-d6, 340K) δ 8.43-8.36 (m, 2H, H-16 & H-19), 8.02 (dd, 1H, JH5,H6=7.8Hz, JH5,H7=1.2Hz, H-5), 7.92-7.91 (m, 2H, H-7 & H-13), 7.64 (m, 2H, H-15 & H-21), 7.57-7.50 (m, 3H, H-6, H-14 & H-20), 3.73-3.46 (bm, 8H, 4× CH2 of morpholine). 13C NMR (75MHz, DMSO-d6, 340K) δ 165.2 (C-4), 156.3 (C-2), 150.3 (C-8a), 138.8/138.4/135.9/135.3 (C-10.
