To a room temperature solution containing 1.59 g of 1-(4-bromo-3-fluorophenyl)-N-methyl-2-(4-morpholinyl)ethanamine (5.02 mmols) in 17 mL of dry DMF was added 2 g of (6,7-dichloro-3-oxo-2,3-dihydro-4H-1,4-benzoxazin-4-yl)acetic acid (7.25 mmols), 2.66 g of BOP reagent (6.02 mmols), and 1.4 mL of triethylamine (10.04 mmols). The reaction mixture was stirred at ambient temperature. After 24 h 10 mL of saturated aqueous NaHCO3 was added. The resulting precipitate was collected, washed with water, and dried in vacuo to afford an off-white solid. MS (ES) m/e 574, 576 [M+H]+.
