Procedure

To tert-butyl 2-((8-(3-(3-fluoro-3-methyl-2-oxoindolin-1-yl)propyl)-1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.2 g, 0.31 mmol) was added concentrated 4M HCl in dioxane (3 mL) and triethylsilane (0.05 mL). After stirring at room temperature for 4 hours, the reaction mixture was concentrated, isolated by preparatory TLC (10% methanol/dichloromethane) and lyophilized with 4M HCl in dioxane (1 mL) to obtain the title compound as a hydrochloride salt (0.073 g, 38%); 1H NMR (DMSO-d6): δ 1.72 (d, 3H, J=23.2 Hz), 1.98-2.07 (m, 4H), 2.72 (t, 2H, J=10 Hz), 3.18 (br, 2H), 3.45-3.72 (m, 4H), 3.76 (t, 2H, J=6.8 Hz), 4.64 (s, 2H), 4.91 (s, 2H), 7.06-7.08 (m, 4H), 7.15 (t, 1H, J=7.6 Hz), 7.24 (d, 1H, J=7.6 Hz), 7.31 (d, 1H, J=7.2 Hz), 7.40-7.46 (m, 2H), 7.57 (t, 2H, J=7.6 Hz), 7.92 (d, 1H, J=8 Hz), 10.27 (br, 1H), 13.21 (s, 1H); MS for C33H34F2N4O4 m/z 589.3 (M+H)+.
