Abstract
Procedure for the preparation of 2-amino-benzylamines of the general formula I **(See formula)** where Hal signifies a chlorine or bromine atom, R1 signifies a hydrogen, chlorine or bromine atom, R2 signifies a cyclohexyl, hydroxycyclohexyl, morpholinocarbonylmethyl or isopropylaminocarbonylmethyl radical, R3 signifies a hydrogen atom or a methyl group and R4 signifies a hydrogen atom or, in case R2 represents an isopropylaminocarbonylmethyl or morpholinocarbmilmethyl radical, it means the benzoyl radical, characterized in that an aldehyde of the general formula II is reacted **(See formula)** where Hal, R1 and R4 are as initially defined, with an amine of general formula III, **(See formula)** wherein R2 and R3 are as initially defined, in the presence of formic acid or the corresponding formamide at elevated temperatures and, if R3 in a compound of general formula III represents a hydrogen atom, it is heated under reflux then the reaction mixture obtained with a dilute acid.
