1065181-58-9, Ethyl 5-bromo-1H-indole-7-carboxylate is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The title compound can also be prepared according to the following procedure: TMSOTf (1.4 ml_, 7.7 mmol) was added dropwise to a solution of tetrahydro-4H-thiopyran- 4-one (0.88 g, 7.6 mmol) in DCM (80 ml.) in the presence of molecular sieves at 0 0C (bath temp). A solution of ethyl 5-bromo-1 /-/-indole-7-carboxylate (2 g, 7.4 mmol). in DCM (20 ml.) was added and the reaction was stirred for 15 min. Triethylsilane (2 ml_, 12.5 mmol) was added and the reaction was allowed to warm to room temperature overnight. Saturated aqueous Na2CO3 was added, the layers separated and the aqueous layer extracted with DCM. The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure. The residue was washed with MeOH and dried in a vacuum oven, giving 2.07 g (76%) of the title compound., 1065181-58-9
As the paragraph descriping shows that 1065181-58-9 is playing an increasingly important role.
