Hydrazine hydrate (1:1) → 3-amino-N,N-dimethylpropane-1-sulfonamide

Participants

Reaction Steps

To a solution of 3-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-propane-1-sulfonic acid dimethylamide (530 mg) in ethanol (10 mL) was added hydrazine monohydrate (0.80 mL) and the reaction was heated at reflux for 3 h. After cooling to room temperature, the mixture was filtered and the filtrate reduced in vacuo to give 3-amino-propane-1-sulfonic acid dimethylamide as a white solid.
