Document Type and Number:
Japanese Patent JPH04506353
Kind Code:
A
Abstract:
The invention concerns a method of preparation of N-alkyl-haloanilines of formula (I), in which X is chlorine or bromine and n is 1 or 2, R<1> is a (C1-C4) alkyl residue, R<2> is a (C1-C6) alkyl residue or R<1> and R<2> form, together with the carbon atom, a five- or six-membered cycloalkane ring, by reacting a halonitrobenzene of formula (II), in which X and n are as defined above, with at least the stoichiometric amount of a carbonyl compound of formula (III), in which R<1> and R<2> are as defined above or R<1> and R<2> form, together with the carbon atom of the carbonyl group, a five- or six-membered cycloalkane ring, in an inert organic solvent at a temperature between about 10 and about 100 DEG C in an atmosphere of hydrogen at an overpressure between about 0 and about 50 bar, in the presence of a platinum catalyst on activated charcoal.
