The present invention relates to a process for preparing pharmacologically active methylamine derivatives and their pharmaceutically acceptable acid addition salts, with the general formula: **(formula)** in which R is n-propyl, isopropyl, isobutyl or allyl and n is 0 or 1. The invention also produces the pharmaceutically acceptable acid addition salts of the compounds of formula I, such as the acid addition salts obtained with an inorganic acid, for example hydrochloric acid, or with an organic acid in which free carboxyl group is attached to a saturated or unsaturated aliphatic radical, or an aromatic or aralkyl radical which may optionally contain a second carboxyl group such as, for example, fumaric acid. |
