52488-36-5,52488-36-5, 4-Bromo-1H-indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
(a) 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-indole. A 50 mL flask was charged with 4-bromoindole (1.00 g, 5.10 mmol), bis(pinacolato)diboron (1.68 g, 6.63 mmol), KOAc (1.44 g, 15.3 mmol) and PdCl2(dppf) CH2Cl2 complex (206 mg, 0.26 mmol) under argon. Dry DMSO (16 mL) was added and the mixture was heated at 90 C. for 4 h. The reaction mixture was cooled, filtered over silica gel and the filter cake was washed with TBME (2¡Á50 mL). The filtrate was washed with brine (3¡Á50 mL), dried (Na2SO4) and concentrated. The residue was purified by flash chromatography (AcOEt/heptane 1:4) to give 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-indole as an off-white solid (1.24 g, quant.).
As the paragraph descriping shows that 52488-36-5 is playing an increasingly important role.
