Procedure

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) (60 mg, 0.08 mmol) in anhydrous CH2Cl2 (1 mL) was added triethylamine (0.054 mL, 0.39 mmol) and the reaction was cooled to 0° C. Methanesulfonyl chloride (0.018 mL, 0.23 mmol) was added and the reaction stirred at 0° C. for 15 minutes. The solvent was removed in vacuo and the residue dissolved in methanol (1 mL) and potassium carbonate (80 mg, 0.58 mmol) was added and the reaction stirred at room temperature for 1.5 h. The reaction was partitioned between CH2Cl2 (10 mL) and water (10 mL) the organic layer was dried (MgSO4) and concentrated in vacuo to afford the title compound as a tan solid (57 mg, 86% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.50-7.86 (m, 10H) 7.33 (br. s., 2H) 5.06-5.21 (m, 1H) 4.04-4.26 (m, 2H) 3.75-4.05 (m, 6H) 3.56-3.72 (m, 6H) 3.38-3.55 (m, 2H) 2.84-3.04 (m, 3H) 2.70-2.86 (m, 1H) 2.40-2.64 (m, 1H) 2.10-2.40 (m, 3H) 1.83-2.09 (m, 2H) 1.20-1.37 (m, 2H) 1.07-1.20 (m, 2H) 0.81-1.07 (m, 12H).
