Reaction Steps

To a suspension of tert-butyl 2-(2,6-difluorophenyl)-4-(5-(4-fluoro-5-(2,2,2-trifluoroacetamido)cycloheptyl)-1-methyl-1H-pyrazol-4-ylcarbamoyl)thiazol-5-ylcarbamate (Diastereomer 2) (28 mg, 0.042 mmol) in MeOH (2 mL) was added a solution of HCl in dioxane (4 M, 1.1 mL, 4.24 mmol) and the mixture was stirred at room temperature for 18 hr. The solvent was removed under reduced pressure and the residue was dissolved in MeOH/water (3 mL/3 mL), treated with K2CO3 (29 mg, 0.21 mmol) and heated at 60° C. for 18 hr. The MeOH was removed under reduced pressure and the aqueous residue was extracted with 5% MeOH/DCM (2×40 mL). The organic layers were combined, passed through a phase separation cartridge and concentrated under reduced pressure to give 358 (Diastereomer 2) as an off-white solid (17 mg, 86% over two steps). 1H NMR (400 MHz, CDCl3) δ 8.44 (s, 1H), 7.76 (s, 1H), 7.34-7.29 (m, 1H), 7.03 (t, J=8.7 Hz, 2H), 6.11 (s, 2H), 4.47-4.29 (m, 1H), 3.83 (s, 3H), 3.23-3.12 (m, 1H), 2.86-2.75 (m, 1H), 2.25-1.84 (m, 6H), 1.60-1.40 (m, 2H). Alkyl NH2 not observed. LCMS (ES+) m/z 465 (M+1)
