Sodium Iodide → 3-[6-(Azetidine-1-carbonyl)pyridin-3-yl]oxy-5-(1-cyclobutyl-2-oxo-pyrrolidin-3-yl)oxy-N-(5-methylpyrazin-2-yl)benzamide

Reaction Steps

To a solution of ethyl 2-[3-[6-(azetidine-1-carbonyl)pyridin-3-yl]oxy-5-[(5-methylpyrazin-2-yl)carbamoyl]phenoxy]-4-methylsulfonyloxy-butanoate (Intermediate 27) (250 mg, 0.41 mmol) in acetonitrile (5 mL), was added sodium iodide (62 mg, 0.41 mmol) and cyclobutylamine (70 μL, 0.81 mmol). The resulting mixture was heated in a microwave at 120° C. for 60 minutes. The solvent was evaporated under reduced pressure and the residue purified by flash chromatography eluting with 0-40% methanol in DCM to afford the product (95 mg, 43%). 1H NMR δ (300 MHz, CDCl3) 1.69-1.78 (2H, m), 2.13-2.23 (5H, m), 2.30-2.40 (2H, m), 2.55-2.64 (4H, m), 3.39-3.47 (1H, m), 3.57-3.64 (1H, m), 4.24 (2H t), 4.62-4.72 (3H, m), 4.91-4.96 (1H, m), 6.96 (1H, t), 7.22 (1H t), 7.36-7.40 (1H, m), 7.45 (1H, t), 8.09-8.13 (2H, m), 8.32 (1H, d), 8.61 (1H, s), 9.51 (1H, d); m/z 543 (M+H)+.
