Procedure

A solution of methyl((1S)-2-methyl-1-{[(2S)-2-(4-{4′-[({[2-((2S)-3-methyl-2-{[(methyloxy)carbonyl]amino}butanoyl)-8,8-dioxido-8-thia-2-azaspiro[4.5]dec-3-yl]carbonyl}amino)acetyl]-4-biphenylyl}-1H-imidazol-2-yl)-1-pyrrolidinyl]carbonyl}propyl)carbamate (108) (107 mg, 0.12 mmol) and ammonium acetate (94 mg, 1.2 mmol) in dioxane (1.5 mL) was degassed with nitrogen and heated to 110° C. in a sealed tube for 18 h. The reaction was cooled to room temperature and diluted with ethyl acetate and filtered and concentrated in vacuo. Purified by SFC to afford the product as a tan solid (39 mg, 37% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.64 (br. s., 10H) 7.32 (br. s., 2H) 5.05-5.24 (m, 1H) 4.04-4.29 (m, 1H) 3.99 (br. s., 1H) 3.81 (br. s., 1H) 3.55-3.73 (m, 6H) 3.03-3.25 (m, 4H) 1.80-2.47 (m, 14H) 0.68-1.06 (m, 16H).
