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.
