Procedure
To a stirring solution of 8-chloro-3-(chloromethyl)-2-(2-(trifluoromethoxy)-phenyl)quinoline hydrochloride (0.6319 g, 1.546 mmol) in DMF (7.732 mL, 1.546 mmol) was added sodium azide (0.2011 g, 3.093 mmol) at room temperature and the mixture was stirred at room temperature. After 1 h, the mixture was partitioned between EtOAc (100 mL) and H2O (100 mL). The organic layer was washed with brine (50 mL×1), dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography on a 40 g of Redi-Sep™ column using 0 to 50% gradient of EtOAc in hexane over 14 min, then 50% isocratic of EtOAc for 5 min as eluent to give 3-(azidomethyl)-8-chloro-2-(2-(trifluoromethoxy)phenyl)quinoline as a colorless syrup: 1H NMR (400 MHz, DMSO-d6) δ ppm 8.66 (1 H, s), 8.11 (1 H, dd, J=8.2, 1.2 Hz), 8.02 (1 H, dd, J=7.6, 1.4 Hz), 7.54-7.74 (5 H, m), 4.52 (2 H, br. s.); LC-MS (ESI) m/z 379.0 [M+H]+.
