Reaction Steps

A solution of methyl 10-(((dimethylamino)(oxo)acetyl)(methyl)amino)-3-hydroxy-4-oxo-4,6,7,8,9,10-hexahydro-7,10-ethanopyrimido[1,2-a]azepine-2-carboxylate (0.10 g, 0.246 mmol), (2,6-dibromo-4-fluoro-3-methylphenyl)methanamine (0.225 g, 0.758 mmol) and Et3N (0.279 mL, 2 mmol) in EtOH (5 mL) was heated at reflux for 48 h. Then, cooled and purified by preparative HPLC to afford the title compound (0.0906 g, 0.138 mmol, 56% yield) as a white solid after crystallization from methanol/H2O. 1H NMR (500 MHz, CDCl3) δ: 12.18 (1 H, s), 9.08 (1 H, s), 7.32 (1 H, d, J=8.5 Hz), 4.96 (2 H, d, J=8.2 Hz), 4.78-4.90 (1 H, m), 3.57-3.72 (1 H, m), 3.36-3.49 (1 H, m), 2.94 (3 H, s), 2.93 (3 H, s), 2.76 (3 H, s), 2.48-2.54 (1 H, m), 2.34 (3 H, d, J=2.1 Hz), 2.00-2.10 (4 H, m), 1.71-1.87 (2 H, m), 1.45-1.53 (1 H, m). LCMS (M+H) calcd for C25H29Br2FN5O5: 656.05; found: 656.24.
