Chemical Properties
White Solid
Uses
tert-Butyl 5-bromoindoline-1-carboxylate is a brominated indoline derivative and a product of biocatalyzed halogenation of nucleobase analogs. It is used in the synthetic preparation of biologic ally active compounds such as selective human β3 adrenergic receptor agonists.
Synthesis
22190-33-6
24424-99-5
261732-38-1
To a solution of 5-bromo-2,3-dihydro-1H-indole (2.11 g, 10.7 mmol) in tetrahydrofuran (THF, 40 mL) was added di-tert-butyl dicarbonate (Boc2O, 2.56 g, 11.7 mmol). The reaction mixture was stirred at room temperature for 18 hours. After completion of the reaction, the mixture was concentrated under reduced pressure. Purification of the residue by fast column chromatography (eluent: hexane solution of 8% ethyl acetate) afforded tert-butyl 5-bromo-2,3-dihydro-1H-indole-1-carboxylate (2.59 g, 95% yield) as a white solid; mass spectrometry (MS) showed the molecular ion peak (M + H)+ m/z = 298.
