Procedure
To a solution of methyl 3-((4-oxo-8-(3-(2-oxobenzo[d]thiazol-3(2H)-yl)propyl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.17 g, 0.3 mmol) in methanol (3 mL) was added lithium hydroxide monohydrate (0.025 g, 0.6 mmol) in water (1 mL). After stirring at room temperature for 18 h, the reaction mixture was concentrated in vacuo and isolated by preparatory TLC (10% methanol/dichloromethane) to obtain the title compound (0.06 g, 36%); 1H NMR (DMSO-d6): δ 1.60 (d, 2H, J=14 Hz), 1.85 (t, 2H, J=5.6 Hz), 2.48-2.53 (m, 7H), 2.66-2.75 (m, 4H), 4.04 (t, 2H, J=8.4 Hz), 4.59 (d, 2H, J=8.4 Hz), 6.77 (t, 1H, J=7.6 Hz), 6.85 (d, 2H, J=8.4 Hz), 7.18-7.24 (m, 3H), 7.33 (t, 1H, J=7.2 Hz), 7.45-7.51 (m, 3H), 7.64 (d, 1H, J=7.2 Hz), 7.85 (d, 2H, J=8 Hz); MS for C31H32N4O4S m/z 556.95 (M+H)+.
