Procedure

tert-Butyl 3((4-oxo-8-(3-(2-oxoindolin-3-yl)propyl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.29 g, 0.488 mmol) and 4M hydrochloric acid/1% triethylsilane in 1,4-dioxane (6 mL) were stirred at room temperature for 4 hours. The reaction was evaporated and the residue purified by PTLC (10% methanol/dichloromethane). The product obtained from PTLC was redissolved in 4M hydrochloric acid in dioxane and evaporated. The residue was dissolved in acetonitrile (5 mL) and water (5 mL) and lyophilized to give product as a white solid (0.25 g, 90%); HPLC rt 9.32 min; NMR (DMSO-d6); δ1.82 (m, 4H); 1.89 (d, J=14 Hz, 2H); 2.94 (m, 2H); 3.16 (m, 2H); 3.44-3.54 (m, 5H); 4.64 (s, 4H); 6.79 (t, J=7.2 Hz, 1H); 6.84 (d, J=7.6 Hz, 1H); 6.97 (m, 1H); 7.01 (d, J=8.4 Hz, 2H); 7.17-7.23 (m, 3H); 7.32 (d, J=7.6 Hz, 1H); 7.49-7.58 (m, 2H); 7.87-7.89 (m, 2H); 10.38 (br s, 1H); 10.44 (s, 1H); 13.0 (br s, 1H); MS for C32H34N4O4 m/z 539 (M+H)+.
