52488-36-5, 4-Bromo-1H-indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,52488-36-5
To a solution of 4-bromo-1H-indole (LXX) (10 g, 50.8 mmol, 1 eq), DMAP (622 mg, 5.1 mmol, 0.1 eq) and TEA (10.6 ml, 76.1 mmol, 3 eq) in DCM (200 mL) was added Boc2O (14.4 mL, 61 mmol, 1.2 eq) at 0C. The reaction was warmed to room temperature and stirred for 2 h. Water (200 mL) was added and the mixture was extracted with DCM twice. The solvent was evaporated under vacuum to give tert-butyl 4-bromo-1H-indole-1-carboxylate (LXXI) as white solid (11.4 g, 38.5 mmol, 76% yield). 1H NMR (CDCI3, 400 MHz) delta ppm 1.68 (s, 9H), 6.64 (d, J=4Hz, 1H), 7.17 (t, J=8.4Hz, 1H), 7.39 (d, J=7.6Hz, 1H), 7.64 (d, J=3.2Hz, 1H), 8.11 (d, J=8.0Hz, 1H); ESIMS found for C13H14BrNO2 m/z 297.1 (M+H).
52488-36-5 4-Bromo-1H-indole 676494, aindole-building-block compound, is more and more widely used in various fields.
