Versuchsvorschrift

tert-Butyl 3-((4-oxo-8-(3-(2′-oxospiro[cyclopropane-1,3′-indoline]-1′-yl)propyl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.27 g, 0.435 mmol) and formic acid (4 mL) were stirred at room temperature for 20 hours. The reaction was evaporated to dryness and the residue purified by PTLC (10% methanol/dichloromethane) to give product as an oil; 1H NMR (DMSO-d6); 61.52 (m, 2H); 1.59 (m, 2H); 1.68 (d, J=13.6 Hz, 2H); 1.87 (m, 2H); 2.57-2.62 (m, 4H); 2.91 (m, 4H); 3.82 (t, J=6.4 Hz, 2H); 4.60 (s, 2H); 4.62 (s, 2H); 6.76 (t, J=7.2 Hz, 1H); 6.86 (d, J=8.4 Hz, 2H); 6.96-7.03 (m, 2H); 7.17-7.23 (m, 4H); 7.48-7.55 (m, 2H); 7.87-7.89 (m, 2H); 8.15 (s, 1H). The formate salt was dissolved in 4M hydrochloric acid in 1,4-dioxane (5 mL) and then evaporated under vacuum. The residue was dissolved in acetonitrile (5 mL) and water (5 mL) and lyophilized to give product as a white solid (0.17 g, 65%); HPLC rt 10.65 min; 1H NMR (DMSO-d6); δ1.54 (m, 2H); 1.62 (m, 2H); 1.90 (d, J=14.4 hz, 2H); 2.11 (m, 2H); 2.92-2.98 (m, 2H); 3.22 (m, 2H); 3.46-3.70 (m, 4H); 3.85 (t, J=7.2 hz, 2H); 4.64 (s, 2H); 4.65 (s, 2H); 6.79 (t, J=7.6 hz, 1H); 7.00-7.06 (m, 4H); 7.19-7.29 (m, 4H); 7.49-7.58 (m, 2H); 7.87-7.89 (m, 2H); 10.6 (br s, 1H); 13.1 (br s, 1H); MS for C34H36N4O4 m/z 565 (M+H)+.
