Methyl 4-bromobenzoate Usage And Synthesis

Chemical Properties

WHITE CRYSTALS OR CRYSTALLINE POWDER

Uses

Methyl 4-bromobenzoate is used as a starting material in the synthesis of three-carbon-bridged 5-substituted furo[2,3-d]pyrimidine and 6-substituted pyrrolo[2,3-d]pyrimidine and methyl 4-tri-n-butylstannylbenzoate. It is also used to stimulate microbial dechlorination of polychlorinated biphenyls. Further, it is used in the preparation of stable radioiodinating reagent to label monoclonal antibodies for radiotherapy of cancer.

Uses

Methyl 4-bromobenzoate is a halogenated benzoate used as a reagent in organic synthesis. It can be used to stimulate microbial dechlorination of PCBs. By condensing methyl 4-bromobenzoate with 3-buten-1-ol, 4-(4-methylphenyl)butanal can be obtained.

Application

Methyl 4-bromobenzoate may be used in the following syntheses:

1. Methyl 4-(2-pyridyl)benzoate by cross coupling reaction with lithium 2-pyridyltriolborate.
2. Methyl 4-imidazo[1,2-a]pyridin-3-ylbenzoate by ligand-free Pd(OAc)2 catalyzed reaction with Imidazo[1,2-a]pyridine.
3. Methyl (E)-4-[3-(2-methoxycarbonylvinyl)-thiophen-2-yl]acrylate by reacting with methyl (E)-3-(thiophen-3-y)lacrylate.

General Description

Methyl 4-bromobenzoate is a para-substituted aryl bromide. Mol-ecules of methyl 4-bromobenzoate are almost planar. The compound is isostructural with methyl 4-iodo-benzoate. The Zeeman effect on the N.Q.R. (nuclear quadrupole resonance) of methyl 4-bromobenzoate on single crystals, has been investigated by the ′geometric method′.

Purification Methods

Crystallise the ester from MeOH. EtOH (m 81o, also 80.5o, 79.5o) or *C6H6/pet ether (m 78-79o). [Beilstein 9 H 352, 9 III 1405, 9 IV 1017.]
