Reaction Steps
To a mixture of 2-(2-(4,5-dichloro-2-iodophenoxy)pyridin-4-yloxy)ethanamine (30 mg, 0.07 mmol), Et3N (35.7 mg, 0.35 mmol) in DCM (5 mL), 2-chloroethanesulfonyl chloride (11.5 mg, 0.07 mmol) was added and the resulting mixture was stirred at room temperature for 1 h. Then solvent was removed under reduced pressure. The residue was taken in THF (2 mL) and H2O (2 mL), then K2CO3 (100 mg) was added and the resulting mixture was stirred at room temperature for 1 h. The mixture was partitioned between DCM and water. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by flash column chromatography on silica gel (DCM/ethyl acetate=5:1) to afford the desired product (56 mg, 56% yield). 1H NMR (400 MHz, CDCl3) δ: 7.98 (d, J=5.6 Hz, 1H), 7.92 (s, 1H), 7.25 (s, 1H), 6.61-6.57 (m, 2H), 6.47 (d, J=2.0 Hz, 1H), 6.32 (d, J=16.4 Hz, 1H), 6.00 (d, J=10.0 Hz, 1H), 4.77 (t, J=5.2 Hz, 1H), 4.18 (t, J=5.2 Hz, 2H), 3.51-3.47 (m, 2H). ESI-MS m/z: 515.0[M+H]+.
