The invention relates to a process for preparing an α-aminoacetal, or addition salts thereof, of formula (I) in recemic form comprising the steps consisting in: reacting a glyoxal monoacetal of formula (II) with an arylalkylamine of formula (III) in such a way as to obtain an imine of formula (IV); adding a Grignard reagent of formula R3-Mg-HaI to said imine of formula (IV) so as to obtain an amine of formula (V), and - deprotecting the amine of formula (V) in such a way as to obtain the compound of formula (I) in racemic form, and, where appropriate, adding an inorganic or organic acid in order to obtain an addition salt of the α-aminoacetal of formula (I).
Process for the preparation of primary amines of formula (I):
where R3 represents an alkyl, cycloalkyl or aralkyl group, by reaction of a triazolium salt of formula (II):
where R1 and R2 represent hydrogen or an alkyl, aralkyl or aryl group, R4 represents an alkyl or aralkyl group or a residue of an organic polymer functionalized by an alkylating group, and A
