3-Ethynylaniline Chemical Properties,Uses,Production

Chemical Properties

Clear yellowish to brown liquid

Uses

Reagent in the preparation of a labelled metabolite of Erlotinib (E625000).

Uses

3-Aminophenylacetylene is used as a pharmaceutical intermediate.

Application

3-Ethynylaniline may be used in the synthesis of the following benzoxazine monomers: bis{4-[3-(3-ethynylphenyl)(2H,4Hbenzo[3,4-e]1,3-oxazin-6-yloxy)]phenyl}phenylphosphino-1-one, [3-(3-ethynylphenyl)(2H,4Hbenzo[3,4-e]1,3-oxazaperhydroin-6-yl)][3-(3-ethynylphenyl)(2H,4H-benzo[3,4-e]1,3-oxazin-6-yl)]phenylphosphino-1-one, and bis[3-(3-ethynylphenyl)(2H,4Hbenzo[3,4-e]1,3-oxazin-6-yl)oxy]phenylphosphino-1-one.
It may be used: To synthesize succin(m-ethynyl)dianilide and sebaco(m-ethynyl)dianilide. As a reagent in the multi-step synthesis of erlotinib hydrochloride. To prepare 3-(3-ethynylphenyl)-6-methyl-2H, 4H-benzo[e]1,3-oxazine. To prepare 3-[3-(4-acetylamino-benzyl)-[1,2,4]oxadiazol-5- yl]-N-(3-ethynyl-phenyl)-propionamide.

General Description

3-Ethynylaniline is a terminal alkyne that can be prepared by the reduction of 3-ethylnylnitrobenzene.

reaction suitability

reaction type: click chemistry

Synthesis

Starting with m-nitrocinnamic acid: First, it undergoes an addition reaction with liquid bromine in glacial acetic acid to generate 3-(3-nitro)phenyl-2,3-dibromopropionic acid; subsequently, it undergoes dehydrobromination and decarboxylation reactions under the action of an organic base (such as DBU) to generate the key intermediate m-nitrophenylacetylene; finally, the nitro group is reduced to an amino group using iron powder in an acidic aqueous ethanol solution to obtain the target product 3-Ethynylaniline.
