5-Bromopyrimidine Chemical Properties,Usage,Production

Description

5-Bromopyrimidine is an important structural unit in organic compounds, featuring a bromine functional group on its pyrimidine ring which serves as the active moiety enabling participation in diverse chemical reactions. Through acid-catalysed electrophilic alkylation of aromatic compounds with 5-bromopyrimidine, followed by oxidative rearrangement to form the dihydropyrimidine ring. Subsequent Sonogashira cross-coupling enables the preparation of 4-aryl-5-pyrimidylacetylene derivatives, which possess medicinal value.

Chemical Properties

yellow solid crystalline, insoluble in water, soluble in organic solvents such as benzene and toluene.

Uses

5-Bromopyrimidine was used in the synthesis of N-heteroaryl substituted 9-arylcarbazolyl derivatives via palladium-catalyzed aerobic and ligand-free Suzuki reaction, (5-(phenylethynyl)pyrimidine) via microwave assisted organic synthesis (MAOS) Sonogashira protocol.

Uses

5-Bromopyrimidine was used in the synthesis of:
N-heteroaryl substituted 9-arylcarbazolyl derivatives via palladium-catalyzed aerobic and ligand-free Suzuki reaction
(5-(phenylethynyl)pyrimidine) via microwave assisted organic synthesis (MAOS) Sonogashira protocol
Intermediate for the synthesis of plant growth regulator flurprimidol

Application

5-Bromopyrimidine is a compound useful in organic synthesis.

Preparation

5-Bromopyrimidine is prepared by reacting dibromodifuranone with formamide in the presence of B2O2 catalyst at 180-185°C to obtain the product.

General Description

Rapid nucleophilic displacement reactions of 5-bromopyrimidine with nucleophiles under microwave irradiation has been studied. 5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine.
