Reaction Steps

To a suspension of 5-benzyloxy-1-{2-[(2S,4R)-2-(3-chloro-2-fluoro-benzylcarbamoyl)-4-fluoro-pyrrolidin-1-yl]-2-oxo-ethyl}-1H-indole-3-carboxylic acid amide Example 503 (148 mg, 0.255 mmol) in TFA (2.5 mL), cooled to 0° C., was added thioanisole (0.301 mL, 2.55 mmol), and the reaction mixture was stirred at RT for 3 h. Volatiles were evaporated under reduced pressure, and the residue was suspended in a saturated aqueous NaHCO3 solution, followed by freeze-drying in vacuo. The residue was suspended in a small amount of methanol and the solid was filtered off. The filtrate was purified by preparative HPLC (Sunfire, C18-ODB, 5 μm, 30×100 mm, flow: 40 mL/min, 20-100% CH3CN/H2O/20 min, 100% CH3CN/2 min, CH3CN and H2O containing 0.1% TFA). The title compound was obtained as a white solid. MS (LC/MS): 491 [M+H]+; 983 [2M+H]+; tR (HPLC, conditions b): 3.75 min.
