実験手順

To tert-butyl 3-((1-(4-fluorophenyl)-4-oxo-8-(3-(2′-oxospiro[cyclopropane-1,3′-indoline]-1′-yl)propyl)-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (2.84 g, 0.31 mmol, 1 equiv) was added concentrated formic acid. After stirring at room temperature for 16 hours, the reaction mixture was concentrated in vacuo and purified using the Biotage flash chromatography system (SNAP 50 g cartridge, Rf=0.5, gradient—1%-15% methanol in dichloromethane). The pure fractions were evaporated to dryness under reduced pressure. The pure residue was converted to the hydrogen chloride salt using 4M hydrogen chloride solution in dioxane. The resulting residue was lyophilized in acetonitrile/water (1:1) to obtain the title compound as a hydrogen chloride salt (1.8 g, 70%); 1H NMR (DMSO-d6): δ 1.50 (t, 2H, J=7.6 Hz), 1.57 (t, 2H, J=7.6 Hz), 1.70 (d, 2H, J=14 Hz), 1.83 (t, 2H, J=6.8 Hz), 2.29-2.37 (m, 2H), 2.54 (t, 2H, J=6.4 Hz), 2.87-2.89 (m, 4H), 3.80 (t, 2H, J=6.8 Hz), 4.57 (d, 4H, J=12 Hz), 6.91-7.23 (m, 8H), 7.48-7.51 (m, 2H), 7.86-7.88 (m, 2H), 8.14 (s, 1H); MS for C34H35FN4O4 m/z 583.16 (M+H)+.
