Severely sterically hindered secondary aminoether alcohols are prepared by reacting an organic carboxylic acid or alkali metal salt of an organic carboxylic acid with a sulfonyl halide, a sulfuryl halide, a mixed sulfuryl ester halide or a mixed sulfuryl amide halide to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.
