white to beige crystalline powder

Purification Methods

If the IR indicates the presence of OH, then treat it with an equal weight of PCl5 and heat it at ca 100o for 2hours, cool and pour onto ice + H2O, stir well and filter off the solid. Wash the solid with cold H2O and dry the solid in a vacuum desiccator over P2O5 + solid KOH. Extract the solid with pet ether (b 40-60o), filter off any insoluble solid and cool. Collect the crystalline sulfonyl chloride and recrystallise it from dry Et2O, pet ether or *C6H6/pet ether. If large quantities are available, then it can be distilled under high vacuum. [Fierz-Davaid & Weissenbach Helv Chim Acta 3 2312 1920.] The sulfonamide crystallises from EtOH (m 150.5o) or H2O (m 153o). [Beilstein 11 H 175, 11 II 93, 11 IV 383.]
