Reaction Steps

6-(tert-Butylsulfonyl)-4-chloroquinolin-7-ol (60 mg, 0.196 mmol), K2CO3 (55 mg, 0.392 mmol) and 1-bromo-3-methoxypropane (0.088 ml, 0.785 mmol) in DMF (1 ml) were heated to 70° C. The reaction mixture was partitioned between EtOAc and brine. The aqueous layer was extracted with EtOAc twice and the combined EtOAc layers were dried over Na2SO4, filtered, and concentrated. The residue was purified via Biotage (SNAP Cartridge KP Sil 10 g, 30-75% EtOAc/Hexane) to yield 6-(tert-butylsulfonyl)-4-chloro-7-(3-methoxypropoxy)quinoline (0.071 g, 0.185 mmol, 94% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.33 (s, 9H) 1.99-2.08 (m, 2H) 3.27 (s, 3H) 3.58 (t, J=6.19 Hz, 2H) 4.32 (t, J=6.19 Hz, 2H) 7.73 (s, 1H) 7.76 (d, J=4.80 Hz, 1H) 8.65 (s, 1H) 8.94 (d, J=4.55 Hz, 1H), MS: m/z: 372.1 [M+H]+.
