Sodium hydrosulfide hydrate → Sodium 2-hydroxy-3-sulfanylpropane-1-sulfonate

Participants

Reaction Steps

To sodium 3-chloro-2-hydroxypropanesulfonate hydrate (2.0 g), sodium hydrosulfide hydrate (0.42 g) was added in 10 mL DMF. The mixture was refluxed overnight. When the reaction mixture was cooled down, white solid was isolated, rinsed with ether and acetone to obtain 1.9 g crude sodium 3-mercapto-2-hydroxypropane sulfonate. The crude product was dissolved in water and preferentially precipitated the desired product by adding acetone. The precipitated product was then filtered and dried under vacuum to get 1.04 g of the title compound.
