4-hydroxypiperidine-1-sulfonamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred solution of p-toluenesulfonyl chloride (39.28 mmol) in dichloromethane (160 mL) was added 4-hydroxypiperidine (40.07 mmol) dropwise, followed by 13.7 ml i-Pr2NEt. The mixture was stirred at room temperature for 3 h. Solvent was removed under vacuum and crude product was purified with flash column chromatography to yield 4-hydroxypiperidin sulfonamide (I). Solvent was removed under vacuum and crude product was purified with flash column chromatography
