Process for preparing 3-aminophenylacetylenes |
| abstract |
A process for preparing a 3-aminophenylacetylene compound of formula (5), including: a) reacting a 3-haloaniline compound of formula (1) with an acetylene compound of formula (2) in the presence of a palladium compound, a copper compound, and an amine compound of formula (3) to form an aniline compound of formula (4); b) precipitating the aniline compound of formula (4) in the form of a crystal, and isolating it by solid/liquid separation; and c) reacting the aniline compound of formula (4) with a base to obtain 3-aminophenylacetylene. |
