実験手順

The title compound was prepared by the addition of 2,3,4,9-tetrahydro-1H-betacarboline-1-carboxylic acid ethyl ester (102 mg, 418 μmol), DCE (5 mL), 4-fluorobenzoyl chloride (60 μL, 477 μmol), diisopropyl ethylamine (167 μL, 954 μmol), DMAP (6 mg, 10 mol %) to a 25 mL flask. The solution was allowed to stir at 55° C. under N2 for 17 hours. The solution was concentrated under reduced pressure, and the crude material was chromatographed (SiO2, 100% hexane to 25% EtOAc) to provide 143 mg (63% yield) of title compound; 1H NMR (CDCl3) δ 8.40 (1H, br s), 7.53-7.57 (3H, m), 7.41 (1H, d), 7.10-7.23 (4H, m), 6.19 (1H, s), 4.31 (2H, m), 4.10 (1H, dd), 3.63 (1H, m), 2.87-2.96 (1H, m), 2.78 (1H, dd), 1.36 (3H, t); 13C NMR (CDCl3) 6171, 169, 138, 130, 129, 126, 126, 123, 120, 116, 116, 112, 110, 62, 53, 45, 22, 14; MS (ESI): 367 (MH+).
