2,3-Dichloroquinoxaline Chemical Properties,Uses,Production
Description
2,3-Dichloroquinoxaline (DCQX) can be used as a substrate for nucleophilic aromatic substitution (SNAr) reactions and is a versatile building block for the synthesis of many quinoxaline derivatives. 2,3-Dichloroquinoxaline reacts with 6-aminothiouracil in ethanol/TEA to form 6-amino-2-(3-chloroquinoxalin-2-ylthio)pyrimidin-4(3H)-one. It reacts with cholest-5-en-3-one semicarbazone/thiosemicarbazone to form steriodal cholest-5-en-3-oxazolo and thiazoloquinoxaline.
Chemical Properties
solid
Uses
2,3-Dichloroquinoxaline was used in the synthesis of mono and 2,3-disubstituted quinoxalines. It was used in solid phase synthesis of HPLC chiral stationary phase containing the N,N′-dialkyl-2,3-diaminoquinoxaline group as a linking structure.
Uses
2,3-Dichloroquinoxaline is a dichlorinated quinoxaline derivative with antimicrobial activity. 2,3-Dichloroquinoxaline is used in the preparation of quinoxaline derivatives of cancer chemopreventive a ctivity.
Preparation
To a stirred solution of quinoxaline-2,3(1H,4H)-dione (5.00 g, 1.0 equiv.), POCl3 was added (20 ml) and refluxed at 100 °C for 3h. After completion of the reaction, as indicated by TLC, the reaction mass was distilled under vaccum and quenched with ice cold water. Off white semi solid was formed and is filtered through buchner funnel under vaccum to yield the 2,3-dichloroquinoxaline in excellent yield.
Appearance: off white solid; Yield: 92% (5.64g); ESI-MS: (m/z) calcd. for C8H4Cl2N2: 197.98, found: 199.10 [M+H]+.
General Description
Gray solid. Insoluble in water.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A halogenated amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Fire Hazard
2,3-Dichloroquinoxaline is probably combustible.
Synthesis
15804-19-0
2213-63-0
General procedure for the synthesis of 2,3-dichloroquinoxaline from 2,3-dihydroxyquinoxaline: a mixture of quinoxaline-2,3(1H,4H)-dione (1) [16] or compound 2 (40 mmol) with phosphoryl chloride (100 mmol) in N,N-dimethylformamide (20 mL) was stirred and reacted for 4 hr at 50 °C. Upon completion of the reaction, the reaction mixture was slowly poured into an ice/water mixture and neutralized with 30% ammonia solution. The resulting precipitate was collected by filtration and purified by column chromatography, the eluent being a solvent mixture of petroleum ether (60-80°C fraction) and ethyl acetate (9:1, v/v).
Purification Methods
Recrystallise it from *C6H6 and dry it in a vacuum [Cheeseman J Chem Soc 1804 1955, Beilstein 23/7 V 144].
