Reaction Steps

The intermediate 1-methylcyclopropane-1-sulfonamide was prepared based on previously reported method (Synlett 2006, 5, 725-278) (Scheme 2). N-(tert-butyl)-1-methylcyclopropane-1-sulfonamide was synthesized using a one-pot procedure from N-(tert-butyl)-3-chloropropane-1-sulfonamide through n-BuLi promoted intramolecular cyclization, lithiation and alkylation with methyl iodide. The removal of the Boc protecting group with TFA afforded 1-methylcyclopropane-1-sulfonamide.
