Procedure
To a stirred solution of 10-amino-N-(4-fluorobenzyl)-3-hydroxy-4-oxo-4,6,7,8,9,10-hexahydro-7,10-(epoxymethano)pyrimido[1,2-a]azepine-2-carboxamide (70 mg, 0.187 mmol) and 2-(dimethylamino)-2-oxoacetic acid (32.8 mg, 0.280 mmol) in DMF (3 mL) was added diisopropyl-ethylamine (0.175 mL, 1.002 mmol), 4-(dimethylamino)pyridine (DMAP) (4.57 mg, 0.037 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (107 mg, 0.280 mmol) and the resulting mixture stirred at room temperature for 3 h. After work-up the crude was purified by preparative HPLC to afford the title compound as an off-white solid (35 mg, 40% yield). 1H NMR (500 MHz, CDCl3) δ: 12.11 (s, 1H), 8.73 (brs, 1H), 7.47 (s, 1H), 7.34 (dd, 2H, J=8.39 & 5.34 Hz), 6.98-7.03 (m, 2H), 4.62-4.70 (m, 2H), 4.53 (d, 2H, J=6.71 Hz), 4.49-4.52 (m, 1H), 4.29 (d, 1H, J=11.6 Hz), 4.08 (d, 1H, J=16.79 Hz), 3.21 (s, 3H), 2.89 (s, 3H), 2.46-2.53 (m, 1H), 2.33-2.38 (m, 1H), 1.86-1.92 (m, 1H), 1.53-1.58 (m, 1H). LCMS (M+H)=474.24. HPLC purity>95%.
