実験手順

To a stirred solution of 10-amino-N-(4-fluorobenzyl)-3-hydroxy-4-oxo-4,6,7,8,9,10-hexahydro-7,10-ethanopyrimido[1,2-a]azepine-2-carboxamide (50 mg, 0.134 mmol) in CH2Cl2 (2 mL) at 0° C. was added Et3N (0.094 mL, 0.671 mmol) followed by methyl 2-chloro-2-oxoacetate (0.1 mL, 0.671 mmol) and the resulting mixture was stirred at room temperature. After 16 h, the reaction mixture was concentrated to give crude product which was dissolved in EtOH (2 mL), treated with 2M dimethylamine/methanol (0.7 mL) and heated in a sealed tube at 85° C. for 2 h, cooled and purified by preparative HPLC to afford the title compound as a light yellow solid (9 mg, 13% yield). 1H NMR (500 MHz, CDCl3) δ: 12.00 (s, 1H), 8.60 (s, 1H), 8.17 (s, 1H), 7.36 (dd, 2H, J=8.55 and 5.49 Hz), 7.00-7.04 (m, 2 Hz), 4.54 (d, 2H, J=6.1 Hz), 4.16 (d, 2H, J=3.66 Hz), 3.28 (s, 3H), 2.91 (s, 3H), 2.50-2.56 (m, 3H), 2.06-2.10 (m, 2H), 1.92-1.99 (m, 2H), 1.70-1.74 (m, 2H). LCMS (M+H)=472.37. HPLC purity: >95%.
