Abstract

Process for the preparation of new 1,4-benzodioxane compounds of the general formula ** (See formula) ** in which NR1R2 means the amino group or an aliphatic or heterocyclic mono- or di-substituted group, R means hydrogen or a lower alkyl radical, Y means hydrogen, a halogen atom, a hydroxyl group, a lower alkyl group or a lower alkoxy group and n means 1,2,3,4 or 5 as well as its non-toxic salts with inorganic or organic acids, characterized in that the aminocarbonyl group of a compound of the general formula II ** (See formula) ** in which NR1R2, R, Y and n have the meaning already expressed, it is reduced with lithium aluminum hydride to the methylene group and, if desired, the compound thus obtained of the general formula I is converted into a salt with an inorganic or organic acid.
