HCID 866592846-(2-Azidopropan-2-yl)quinolineYield 60%

Procedure

2-(Quinolin-6-yl)propan-2-ol (0.50 g, 2.67 mmol) and sodium azide (1.73 g, 26.70 mmol) were added successively to ice-cold trifluoroacetic acid (20 ml) and warmed to room temperature. After 12 h, the reaction mixture was cooled to 0° C., quenched with water and basified with sodium hydroxide solution and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure to afford the title compound as brown liquid (0.340 g, 60%). 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 8.90 (dd J=4.1, 1.6 Hz, 1H), 8.41 (d, J=7.6 Hz, 1H), 8.06 (d, J=2.1 Hz, 1H), 8.04 (d, J=9.0 Hz, 1H), 7.88 (dd, J=8.1, 2.2 Hz, 1H), 7.56 (q, J=4.2 Hz, 1H), 1.71 (s, 6H).
