実験手順

To a solution of methyl [(1S)-2-methyl-1-({(2S)-2-[4-(4′-{2-[6-((2S)-3-methyl-2-{[(methyloxy)carbonyl]amino}butanoyl)-2,6-diazaspiro[3.4]oct-7-yl]-1H-imidazol-4-yl}-4-biphenylyl)-1H-imidazol-2-yl]-1-pyrrolidinyl}carbonyl)propyl]carbamate (Example 24) (45 mg, 0.06 mmol) in anhydrous CH2Cl2 (0.6 mL) was added methyl isocyanate (0.01 mL, 0.17 mmol) and the reaction stirred at room temperature for 2 h. The solvent was removed in vacuo and the residue dissolved in methanol (1 mL) and potassium carbonate (40 mg, 0.29 mmol) was added and the reaction stirred at room temperature for 18 h. The reaction was partitioned between CH2Cl2 (10 mL) and water (5 mL), the aqueous layer was extracted with CH2Cl2 (5 mL), the organic layers were combined and dried (MgSO4) and concentrated in vacuo to afford the title compound as a yellow solid (34 mg, 70% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.64 (br. s., 10H) 7.33 (br. s., 2H) 5.06-5.22 (m, 1H) 4.03-4.46 (m, 3H) 3.73-4.04 (m, 8H) 3.54-3.73 (m, 6H) 3.46 (q, J=7.0 Hz, 2H) 2.52-2.76 (m, 5H) 2.10-2.53 (m, 4H) 2.02 (br. s., 3H) 0.70-1.09 (m, 12H). HRMS for C44H57N10O7 (M+H)+ calc: 837.4412, found: 838.4416. Purity (LC-MS): 91%.
