Methylamine derivatives of the formula: ##STR1## and pharmaceutically acceptable acid addition salts thereof, wherein R.sub.1 and R.sub.3 each represent a hydrogen atom or a straight- or branched-chain alkyl, alkenyl or alkynyl radical containing from 1 to 6 carbon atoms, R.sub.2 represents a straight- or branched-chain alkyl, alkenyl or alkynyl radical containing from 2 to 7 carbon atoms with the proviso that when R.sub.2 represents an alkenyl radical of the formula CH.dbd.CH--R.sub.6 or an alkynyl radical of the formula C.tbd.C--R.sub.6, in which R.sub.6 represents a hydrogen atom or a straight- or branched-chain alkyl radical of 1 to 5 carbon atoms, R.sub.1 and R.sub.3 each represent an atom of hydrogen or an alkyl radical, R.sub.4 and R.sub.5, which are the same or different, each represent a hydrogen atom, a straight- or branched-chain alkyl, alkenyl or alkynyl radical containing from 1 to 5 carbon atoms or an .omega.-hydroxyalkyl radical containing from 2 to 5 carbon atoms or R.sub.4 and R.sub.5, when they are taken together represent an alkylene radical containing from 2 to 6 carbon atoms, an alkylidene radical containing from 1 to 5 carbon atoms or the radical --CH.sub.2 --CH.sub.2 --O--CH.sub.2 --CH.sub.2 --, R.sub.1, R.sub.2 and R.sub.3 being such that the trisubstituted methylamine radical possesses no more than 13 carbon atoms. They are useful for treating Parkinson's disease and for correcting extra-pyramidal disturbances provoked by neuroleptics.
