A range of aminonitriles, readily available by Strecker reaction, were forced to react with methyl 2-(chlorosulfonyl)acetate. Methyl 2-[[(cyanoalkyl)amino]sulfonyl]acetates formed on the first stage without isolation were converted to methyl 4-amino-

Comparison of the title compound, C20H28N2O5S, with related structures shows that the presence of the alkyl substituents influences the conformation of the rings in the frame fragment. The molecules form hydrogen-bonded centrosymmetric dimers due t
