Procedure

A solution of tert-butyl 2-((8-(3-(3-cyclopropyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl)propyl)-1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (240 mg, 0.367 mmol, 1 equiv) in 4M hydrogen chloride solution in dioxane was stirred at ambient temperature for 5 h. The mixture was concentrated in vacuo and purified using preparative thin layer chromatography in 10% methanol in dichloromethane to afford the title compound as a white powder (72 mg, 33%); 1H NMR (400 MHz, DMSO-d6): δ 0.84-0.88 (m, 2H); 0.99-1.04 (m, 2H); 1.76 (d, 2H, J=13.6 Hz); 1.87 (bs, 2H); 2.41 (bs, 2H); 2.84-2.88 (m, 1H); 3.85 (t, 2H, J=6.8 Hz); 4.60 (s, 2H); 4.89 (s, 2H); 6.92-6.95 (m, 2H); 7.01-7.11 (m, 4H); 7.18-7.22 (m, 2H); 7.28 (d, 1H, J=7.6 Hz); 7.40 (t, 1H, J=7.6 Hz); 7.57 (t, 1H, J=8 and 7.2 Hz); 7.90 (d, 1H, J=6.8 Hz); 12.9 (bs, 1H); MS for C34H36FN5O4 m/z 598.4 (M+H)+.
