Abstract
A process for the preparation of 2-aryl-2-aminomethyl-dioxolanes- (13) of the general formula ** as well as its salts and quaternary ammonium compounds of the general formula ** (see formula) ** where they mean: R and/or r '= hydrogen or a free or- or p-stable hydroxyl group closed by a carbon structure with 1-10 c atoms; R1 = hydrogen or a branched or unbranched alcohol radical with 1-4 c atoms; R2 and/or r3 = hydrogen or a branched or unbranched alkyl radical with 1-4 co atoms an oxyalcohyl radical or a cycloalkohyl radical or an aralkyl radical. The radicals r2 and r3 can be equal to each other or can be formed together with the atom of nitrogenoun hydrated heterecyclic ring of 4-6 members, the case can contain another hetere atom pe a pyrrolidinicopiperidinic or morpholinic ring; R4 = hydrogen or a branched or unbranched alkyl radical with 1-4 co atoms a cycloalkohyl radical or an aralkyl radical; C = an inorganic or organic acid radical preferably halogen or -ch3 so4 characterized by reacting 2-aryl-2-halogenomethyl-dioxolanes- (13)...
