Procedure
To a stirred solution of tert-butyl N-((4R,5S)-1-(4-((5-(tert-butoxycarbonylamino)-2-(2,6-difluorophenyl)thiazole-4-carbonyl)amino)-2-methyl-pyrazol-3-yl)-5-hydroxy-azepan-4-yl)carbamate (199 mg, 0.30 mmol) in DMF (2 mL) at 0° C. was added sodium hydride (60% dispersion in oil, 26 mg, 0.66 mmol). The mixture was allowed to warm to room temperature over 2 hr, quenched with water (3 mL) and the resulting precipitate filtered off and dried under reduced pressure. The aqueous layer was extracted with EtOAc (3×3 mL) and the combined organic layers were passed through a phase separation cartridge, concentrated under reduced pressure and the residue combined with the precipitate collected earlier. A solution of this material (159 mg, 0.27 mmol) in HCl in dioxane (4 M, 10 mL) and MeOH (5 mL) was stirred at room temperature for 16 hr. The solvents were removed under reduced pressure. Purification via preparative HPLC gave 486 as a white solid (55 mg, 41% over two steps). 1H NMR (400 MHz, CDCl3) δ 8.50 (s, 1H), 7.79 (s, 1H), 7.37-7.28 (m, 1H), 7.05 (t, J=8.8 Hz, 2H), 6.14 (s, 2H), 5.08-5.00 (m, 1H), 4.87 (s, 1H), 4.26 (td, J=9.3, 3.5 Hz, 1H), 3.75 (s, 3H), 3.45-3.33 (m, 2H), 3.16-3.07 (m, 2H), 2.34-2.27 (m, 2H), 2.20-2.09 (m, 1H), 2.06-1.97 (m, 1H).
