Description

General description

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

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
• 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.
