実験手順

9-bromo-10-fluoro-1,3,4,7,8,12b-hexahydro-[1,4]diazepino[7,1-a]isoquinoline-2,5-dione. To a stirred solution of 2-(2-(2-aminoacetyl)-5-bromo-6-fluoro-1,2,3,4-tetrahydroisoquinolin-1-yl)acetic acid (HCl salt) (54.6 g, 143 mmol) and triethylamine (100 mL, 715 mmol) in DCM (570 mL), T3P (125 mL, 215 mmol, 50% m/m in AcOEt) was added slowly (exotherm) and the suspension was stirred at rt for 1 h. The solvent was reduced to a small amount under reduced pressure and the thick suspension was treated with water (500 mL) and the suspension was stirred overnight. The suspension was filtered off and the solid was again treated with water (200 mL), stirred for 10 min and filtered off. The slightly yellow solid was washed with water (1×) and with diethyl ether (2×). The resulting solid was dried at rt under high vacuo overnight to yield the title compound as slightly yellow solid (40.5 g). UPLC-MS: MS 327.1/329.1 (M+H+); UPLC rt 0.73 min.
