Title:
METHOD FOR PRODUCING α-AZIDOANILINE DERIVATIVE OR α, α'-DIAZIDE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2020/004043
Kind Code:
A1
Abstract:
The present invention provides a method which uses an aniline derivative as a starting material, and which is capable of producing an α-azidoaniline derivative or an α, α'-diazide derivative. The present invention comprises a method for producing an α-azidoaniline derivative represented by formula (2) or an α, α'-diazide derivative by bringing an aniline derivative represented by formula (1) and an azidizing agent into contact with each other in the presence of water, a persulfuric acid salt and a copper compound. (In formula (1), each one of R1 to R5 independently represents a hydrogen atom, a halogen atom, a nitro group, a cyano group, a substituted or unsubstituted alkyl group having 1-12 carbon atoms, a substituted or unsubstituted alkoxy group having 1-12 carbon atoms, a substituted or unsubstituted aralkyl group having 7-14 carbon atoms, a substituted or unsubstituted aryl group having 2-13 carbon atoms, a substituted or unsubstituted alkoxycarbonyl group having 2-7 carbon atoms, or a substituted or unsubstituted carbonyl group having 1-20 carbon atoms; or alternatively, adjacent moieties among R1 to R5 may combine together to form an aliphatic hydrocarbon ring, an aromatic ring or a heterocyclic ring. In formula (2), R1 to R3 and R5 are the same as R1 to R3 and R5 in formula (1); and R4 represents an azide group (N3), or is the same as R4 in formula (1).)
