실험 절차

A solution of tert-butyl 2-((8-(3-(3-cyclopropyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl)propyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (230 mg, 0.362 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. The pure extract was treated with 4M hydrogen chloride solution in dioxane to afford the hydrogen chloride salt of the title compound as cream crystals (60 mg, 28.8%); 1H NMR (400 MHz, DMSO-d6): δ 0.86-0.90 (m, 2H); 1.01-1.06 (m, 2H); 1.98 (d, 2H, J=14.4 Hz); 2.13 (bs, 2H); 2.88-2.99 (m, 3H); 3.2 (bs, 2H); 3.65-3.73 (m, 4H); 3.91 (t, 2H, J=6.8 Hz); 4.67 (s, 2H); 4.93 (s, 2H); 6.80 (t, 1H, J=7.2 Hz); 7.01 (d, 2H, J=8.4 Hz); 7.08-7.10 (m, 2H); 7.19-7.24 (m, 2H); 7.26-7.28 (m, 1H); 7.31 (d, 1H, J=7.6 Hz); 7.43 (t, 1H, J=6.8 and 7.6 Hz); 7.55-7.59 (m, 1H); 7.92 (dd, 1H, J=1.2 Hz); 10.50 (bs, 1H); 13.2 (bs, 1H); MS for C34H37N5O4 m/z 580.12 (M+H)+.
